I read the book and found that the ending in the movie was a decent resolution to what had bothered me. Channing Tatum was exactly the way I pictured John in the book, and Amanda Seyfried was wonderful (as she always is.) I didn't like the casting of Alan and the changes made there from the book or the character Tim (liked the one in the book better). Go see it. You'll cry at parts but the ending needed about another minute of resolution. Just my opinion...
This movie will appeal to anyone with a heart...and especially those of us in the South who love the SEC. Sandra Bullock and Tim McGraw do a wonderful job as does the actor playing Michael Oher. Go see this one. We had a full house (in Alabama) and you even heard applause for the different coaches although most of them are at different schools now! Makes you want to look around YOUR life and see the opportunities to reach out and make a difference in your own unique way. Go see it! (and ROLL TIDE) :)
