Yes, I love this film. Although many do not like the films of Sandler, I like them nearly all. Grown Ups has met the test of time, and thus awakened the sense of familiarity. I always meet even early 30s, and have the desire, friends from the past and to organize a Gaudi. Therefore, the film and also Part 2 was very well received with me :)
Sure, on the content of the story one can argue, but it's just light fare so it fits yes :)
