I really enjoyed Toy Story 3 but my 7yr old daughter was really freaked out by Lotso, Big Baby and the other mean toys. So much so that she started to cry during the "time out chair" interrogations and "take him to the box" scenes. From then on, she was upset. We had to leave the theater and wait until after the incinerator scenes. I made sure we came back after the real drama was over so she could see that there was a happy ending. She's not overly sensitive so I think parents need to be aware that this can be scary for some kids.
Other than that I thought the movie was well done.
