I really like 'Alvin and the Chipmunks 4: The Road Chip', at first I was watching it ironically until I realised that it was somehow actually funny. It's a combination of unintentional humour (like how they could afford to hire the guy from LMFAO (pictured) to have a two or three minute speaking role as himself and to promote the film but couldn't afford to have him play any of LMFAO's actual music), rubbish intended humour that's become ironically funny now that the films been out for half a decade and is quite dated (theodore twerking to baby got back) and jokes that were funny in of themselves all along (the chipmunks getting put on a no fly list as suspects in a terrorist attack).
Somehow the film manages to pull it all off and actually achieves its aims despite it having the lowest budget of all the films and seeming the most like a cynical last ditch cash grab made just before the 'franchise' became entirely irrelevant.
So what garbage tier films do you really like?
A Few Good Men.
It's a shitlib imperialist film written by shitlib hack Aaron Sorkin, but the character work and the courtroom drama aspects are so goddamn entertaining. It ends by removing almost all guilt from the murderous thugs Tom Cruise [celeb Scientologist] is defending, but the path to the ending, complete with Jack Nicholson's insane narcissistic monologue, is really fun. Demi Moore gets way less respect than she deserved for her role, the whole script was basically stacked against her. But I still love it despite its many, MANY issues.
12 Angry Men is alright and I think its existence is the only reason A Few Good Men isn't total garbage
