Heh, weird movies, you say? I got some:
Funky Forest
Japanese movie consisting of weird, nonsensical clips. I just kept going "wtf" through most of the movie.
The Amazing Bulk
Very much a "so bad it's good" movie, this just has to be seen to be believed. Terrible GCI, random 3D GIF animations added in (including a one-minute chase scene largely consisting of these, terrible acting, and every single scene is obviously and terribly greenscreened. Worth a watch for a laugh.
Foodfight
Another "so bad it's good" movie... and by "so bad it's good" I mean terrible. Recommended to watch with friends just to be able to get through it. Foodfight features terrible CGI animation and writing, tons of food mascots (product placement, much?), way more innuendo than anyone would consider appropiate for a kids' movie, and food Nazis (yes, I'm serious).
Fun fact: this crap took 10 YEARS and 65 million $ to make, and at one point during development the tapes got stolen and they had to remake everything, delaying the movie significantly. Only reason I'm listing it here is that it has to be seen to be believed.
