A physically handicapped serial killer with massive blue balls is a great idea for a movie (in fact one of the best horror films I've ever seen was an 8-minute short film about a completely physically handicapped man with massive blue balls who goes on a frenzied killing spree...but I forgot the name of the film and I've never been able to find a copy. Does anybody know the name of the film?), but the script for LATE BLOOMER doesn't hold up for the full 83 minutes. Not even close. Trim off 45 minutes and you might have something.
Sumida is physically handicapped as fuck, but he seems to be completely mentally aware and can get around pretty good when it comes to walking. He has two caregivers that help him and one, an older lady, has a cute niece who wants to visit Sumida for a few weeks so she can write a college paper on caring for the handicapped. She comes over an Sumida is smitten with her almost a quickly as she's smitten with Sumida's other caregiver: a handsome singer for a rock band. Sumida is too innocent to even notice this at first, but once he does he goes bonkers and...well, you'll just have to see for yourself, but I don't really recommend that you do cause the shit is too long-winded and boring. Worst of all when it finally gets to the ending it's a complete letdown.
Kudos for the interesting idea and actually casting physically handicapped people in the film, but there's way too much filler.
