Everything is about the horror effects and jump scares. They were vivid and exciting except for the vomiting. That was grossly overused. The design and look of the moisen were freaky as hell. They looked like the little mummies from the Mummy movies. Lol.
February 29 could have been a better horror movie. I felt it was more psychological thriller. The plot is original and the ending is unique. Whether or not you make sense of the ending depends on your perception of the truth.
The first half of the movie could have been executed better to present a better plot twist. Still liked the second half of Hikikomori for its touchingly creepy scenes. :D
