TOY STORY 2 is amazing. Simply put. It's a sequel that does the impossible: surpass the humor, creativity, and positivity of the classic first installment. This is one of, if not the best, kids movies ever. But, just because it's perfect for kids, doesn't mean that adults won't love it. There's more than enough humor and entertainment to satisfy the most mature adult.
Violence might be the only issue in the movie. There is no actual violence short of a toy's arm falling off (but it gets sewn back on again). One toy apparently falls off an elevator to his death, but is safe (and reformed) in the end. Some toys are put in peril, but mostly it's all played for laughs. The movie is one of the most positive Pixar movies out there (and that's a feat). Friendship, loyalty, love, courage, and sacrifice are major elements spoken about frequently in the film. All of the characters, save on greedy human, are great role models.
Do yourself a favor, even if you don't have kids (but especially if you do!): Watch it!
