Journalist character faces no tension in his trip back to New York, because he's good at everything. He has a level head and perfect body. He just casually jogs a half-marathon (with his luggage), after a full day of non-stop travel. When the characters don't care or seem hindered by obstacles, the audience doesn't care either.
