If they don't take themselves too seriously and try to establish some plot where the gang gets mad at each other only to have it resolved in the end in a "happily ever after" plot I think the movie could work. Seriously, just have them do stupid shit for two hours without any real 'objective' to overcome and people will like it, except the dumbest moviegoer who needs a script to be "buildup > resolution".
Really, give me 2 hours of them partying, crashing and being general assholes while Ari calls them every nuance of cunt he can think of and I'll be happy
