Everything about this movie is unbelievable, but the most shocking "I can't even fathom" is that it stars a young Brad Pitt.

Frank (Pitt) is stuck in Cool World after he bullied his mom into taking a motorcycle ride of death. He somehow escapes not only death, but all the consequences and self-blame of an accident was, let's face it, kind of his fault. 

 You can't fully blame Pitt for the way he performs. It's always difficult to act opposite someone who's not actually there (in this case, badly animated characters including the overtly sexual  Holli Would, a "doodle" who is literally DTF any "noid" that will have her), but it's evident from the terrible looking massage he gives his cartoon girlfriend Lonette  that he wasn't given the best direction.

Holli doesn't care that having sex with a human will destroy both worlds, she just wants to be Kim Basinger IRL. Frank is in a long-term (60 years?) relationship with a Doodle who he can't sleep with, for fear of destroying the fabric of their worlds. 

Essentially, this movie is about blue balls.
