Yes the movie was funny, especially Alex Baldwin. Steve Martin has a very underdeveloped role and is barley in the movie. But for me, the end was REALLY disappointing and made no sense. Rent it.
Gosh, don't people know how to suspend belief and just enjoy goofyness. We saw this movie twice, took friends the second time and they loved it too. We laughed heartily for the whole movie. Adam Sandler was so endearing as were all the characters and we loved seeing Lanie Kazan again. We love indie films and Woody Allen and all the old Mel Brooks stuff and loads more. Keep your mind open and relax, you'll have a good time!
My husband and I went with another adult and three kids. It was unanimous, we all loved the movie, the "tricks" were fabulous and everyone was was screaming and hooting at them. It just flew by . It is easy for me to suspend belief and immerse myself, this is the way a movie like this has to be watched. It got a round of applause at he end. I will see it again soon. I'm 65 my husband is 68, our daughter is 42 and the kids are 8, 13 and 15, so it is a pretty good cross section.
