TS3 has some darling scenes. Ken was my favorite character and I loved Andy's message to Bonnie at the end, so I'd say you should go see it. The only reason I didn't give this film an excellent rating is because of all the hair-raising "are they gonna make it?" scenes - think Finding Nemo. After awhile, I tune out and wait for the story to pick back up again.
We are film snobs and rarely go to the movies opting for classics from our AFI collection instead. David Fincher, director, should be congratulated for the restraint and care used to interpret this masterfully written book. Brad Pitt, Cate Blanchett, and Taraji P. Henson were awesome and the story captures your imagination. If you love the craft of film making, check this one out. The love story part of it is heart-stopping.
