I haven't seen it, but it sounds like it falls along the similar lines as "The Wedding Singer" with the 80's references.
nah - wedding singer was a feel good romantic comedy. this is a raunchy, sex, drug, movie for 40yr olds. there is some overlap with WS and the hair metal bands and funny clothes of the 80s but it stops there. This movie will be much more significant for guys that are 38-45 and used to party hard in their early 20s. You dont realize the lens you used to look through the world and there are a lot of things in the movie that demonstrate how much we change as we get older and our views. Package that into an absurd plot that the movie even mocks and some good acting and it was a laugh riot. Somehow today I feel older but not missing the past all that much as it was more complicated than what I can handle today
