The appealing combination of words "korean" and "slasher" pulled me into this one, and indeed it's quite the saucy slasher, but not in the best of senses. Via an unapologetically fast intro we learn that a teacher gives birth to a deformed child, who they don't love and keep in basement, until her husband commits suicide in front of the kid. Sounds like a slasher alright. Cut to present day, a class of that time is visiting the now old and wheelchair-bound teacher, and this dinner party will bring out old grudges. The script of "Bloody Reunion" tries hard to twist a bunch of borrowed tropes, and explore a high count of characters too deep too quickly, establishing plot-points frequently with little behind them. The movie is sort of 50/50 plot/slasher violence driven, and the plot involves serious matters, like psychological trauma through abuse, but as opposed to more acclaimed, focused movies on similar themes, "Bloody Reunion" doesn't allow time or space for substantial development and construction, and rather takes leaps. Visually, the movie is very well serviceable, but unimpressive, and the constant zooming in some dialogue scenes didn't work very well. When it comes to special effects, however, they're gruesome alright. It's a slasher that definitely speaks some effort, and is a decent attraction to the fans of the genre. 6/10.
