Well, that was a pretty disappointing read.
I don't know why it was disappointing, though. Even though Tim Allen was funny on TV and in movies, and despite having a successful comedy/standup career, it doesn't automatically mean that he'd be a good writer. A fun writer, yes, but not necessarily any good.
Although the premise of the book, and the theme it self is amusing, and there are spots around the book that made me laugh really hard (some very funny standup kinda one-liners), the book it self was pretty bland.
It rambles on aimlessly, wading from one subject to another in a very disjointed fashion. I think the whole book might have worked better as a series of blog posts, or something similar. Things that don't necessarily require a beginning or an end, or a central theme.
Overall the book was OK, and if you have it and want to read it then go ahead, but I wouldn't waste my money on it. Sorry Tim.
