Pros:
I liked the Kenyan parts, Deena is so cute, and the other parts about the elites and history of the marathon were good.
Good preview of the Chicago course.
Nice to see a running movie in the theaters.
Cons:
There was way too much about the other marathoners.
Of the slower people only the old guy was likable, the other people seemed to be complainers that just wanted to do the marathon so they say they did it and then get back to overeating. Even the faster of the slow people the 3:11 marathoner guy was almost in tears when he got injured. Yeah, injuries suck but he could not seem to see all the other positive things he had going on in his life like a wife that shares his interests and a healthy baby girl. Also too stereotypical, all the slow people's knees hurt, the Kenyan guy ran 5 miles to and from school (10 miles a day a 7 years old), blah, blah, blah.
All in all was kind of like listening to you neighbor whom has run exactly one marathon in his life and will talk your ear off for several hours by giving you a blow-by-blow recount of it in painful detail.
Worst Line of the Movie (next to John the penguin’s stupidities) Dick Beardsley (who is cool) "The marathon will change your life"
No, now instead of just being a Fatso, you will now be a Fatso who once ran a marathon.
If you did not see it you did not miss much!
