The Maze Runner question

No Griver Hole
The maze in the book is square, and circle in the movie
A knife kills Chucky in the book, a gun in the movie
Bus vs. Helicopter
More survivors in the book, less in the movie

To name a few, there are a ton of differences.

Gary just about summed it up

Well, there was a lot of changes, but quite a few of them I actually preferred for the movie. Telepathy, for instance, could have been strange in the movie. It was cool in the book, but for the movie? Despite all the changes I'm listing, I still loved the movie. Perhaps, not as much as the book, but I thought it was pretty good.

Anyway, here's almost all of the changes I noticed, in chronological order (most of these are stupid, and don't matter at all, lol):
Supplies are brought up only once a month (with the new Greenie), rather than every week.
Thomas runs away from the Gladers (and face-plants) instead of lying against a tree and talking to them.
Thomas is thrown in the Pitt on the first day.
The Box is called the Pitt.
Alby is much nicer to Thomas.
Thomas doesn't remember his name.
Alby gives Thomas a tour on the first day instead of the second.
Alby tells Thomas the '3 rules' on his first day.
Only 1 rule was specified in the book (never go out in the Maze unless you're a Runner)
Newt has short hair instead of long
Most of the Glader slang is (unfortunately) replaced with actual swear words.
Thomas (sort of) tries to go out into the Maze on the first day.
The Gladers have some sort of bonfire and wrestling match(es) at night.
The Gladers have been here for 3 years, not 2.
Thomas remembers his name after getting the wind knocked out of him.
Thomas has dreams about Teresa and keeps hearing "Wicked is good"

Just to be clear, I'm pointing out pretty much every change I noticed, regardless if they were important or not. Why? Because I felt like it :)

Thomas (as well as all the other Gladers) writes his name on this wall.
Thomas goes out in the Deadheads to get fertilizer, instead of just wandering around and stumbling upon the graveyard.
Getting stung by a griever causes you to go insane, rather than the Grief Serum and the Changing.
The banishment poles were just poles that the Keepers used to push Ben into the Maze, and weren't connected or had a collar on the end.
Frypan is called Frycook.
When Teresa arrives she does not have "WICKED is good" written on her arm.
Teresa says, "*gasp* Thomas!" instead of "Everything is going to change."
Teresa has a British accent.
Thomas and Teresa are not telepathic.
She only goes into a coma for a few hours, instead of a few days.
There is a group of people with Thomas, instead of just him and Newt, when he runs out in the Maze at night.
Newt does not say, "Don't you bloody do it!" (I couldn't have been the only person waiting for that, right?)
Minho (apparently pronounced "meen-oh", not "min-ho") helps Thomas lift Alby up the ivy covered wall.
Thomas and Minho use the ivy as a pulley to lift Alby up, rather than Thomas' "push and tie" technique.
Thomas kills a griever.
Minho, Thomas, Zart, Frycook, and Jeff go in the Maze to find the Griever Thomas killed.
They find a Griver heart(?).
When Teresa wakes up, she climbs up this outpost tower and starts hurling rocks at all the guys.
She doesn't remember anything, except her name.
She had two Grief Serums in her pocket; the first two ever.
Teresa is not an annoying smart-alec......well.
Thomas is sentenced to 1 night (sundown to morning) in the Pitt, rather than 1 day (morning to sundown).
Chuck gives Thomas a wooden toy he made to give to his mom.
Minho releases Thomas from the Pitt, instead of Alby.
The Maproom is Minho's own private place to record his finding in the Maze, not all the Runners.
The Maze is a circle, rather than a square.
Thomas and Minho (when running) find the Griever "Hole" in the Maze, due to the Griever's heart.
The Griever Hole is a circular opening in a wall, rather than an invisible square over the Cliff.
There is no Cliff.
The Maze has "blades".
Only certain sections of the Maze open up per a day.
Gally does not go crazy at a Gathering, threaten to kill Thomas, and run into the Maze.
When Teresa triggers the End, the sun does not disappear.
The Grivers do not only kill one a night.
When the Grievers come, Alby dies.
Gally does not get taken by Griever, nor does anyone else.
Thomas grabs the stinger that Alby hit off a Griver (before dying) and stabs it in his leg to enter the Changing, instead of jumping in a swarm of Grievers and getting torn apart.
Thomas wakes up with Teresa in the Pitt.
Gally through Thomas and Teresa in the Pitt and sentenced them to a Banishment.
Gally lied about Banishing them, and planned to sacrifice them instead.
Only about 20 Gladers (not including Gally, since he chose to stay behind), try to leave the Maze through the Griever Hole.
The code is not: Float, Catch, Bleed, Death, Push (am I missing one?), but is the order of the Maze sections opening.
The Gladers go down a hallway, instead of a slimy slide.
All of the creators (and Chancellor Ava Paige) are dead.
Ava Paige "suicides".
The Gladers learn that the Flare has destroyed most of the population from a recording, rather than their "rescuers".
We learn that the Gladers are immune to the Flare.
Gally gets stung by a Griever and shoots Chuck.
Chuck was shot by a gun, instead of getting a knife thrown at him.
Chuck was not forced to jump in front of Thomas.
Gally was not forced to shoot Thomas/Chuck.
Minho throws a spear at Gally.
When the Gladers are "rescued", they are taken away in a helicopter, not a bus.
There are fewer survivors than in the book.
The Maze was an outdoor facility.
The Maze was built right next to the Scorch.

Now. Here's the worst change made in the movie:
Minho was NOT a hilarious sarcastic hothead!

I skipped a few changes, cause this was already way too long ;)

I also found them pretty large. I don't think that the movie went into full depth with the glade settlement before Thomas arrived, among other things.

I just watched the movie and I absolutely hated it, I was disappointed because I thought it would be better. I give the movie a D grade wise.

I loved the movie because it told its own story that was very similar to the book. It has the same memorable parts from the book but i really do like to knit pick. I got the same feeling from the book with the movie. I felt the suspense, I felt the sadness. The changes didn't bother me. I liked them. If i wanted the movie to has the same story as the book i would have just read the book again but the movie took a lot of nice changes to make the Maze Runner feel fresh and new but still be based off the book. I really like the Grievers and there design. Nothing was unexplained or random the characters are still the characters i remembered and I liked the relationship between Gally and Thomas because of the way they talked to each other instead of Gally just hating him and at the end of the movie i don't hate Gally. Thomas and Chuck still have a cute relationship and i cried when he died it didn't matter the weapon it just matter that he is gone and the promise Thomas made to him.
No movie should be exactly like the book if any person whats that just read the book again. This movie is just a good movie anyway when you are not blinded by the book.
