“Happy Death Day 2U,” a follow-up to a 2017 thriller, is the kind of sequel that seems to be in search of a reason to exist. However, that doesn’t necessarily mean it’s bad to watch.
The movie picks up right where the first movie left off. Theresa (Jessica Rothe), who casually goes by Tree, put an end to a time-loop where she was living the same day over and over and in doing so, made several changes to improve her life.
However, she soon finds out that her issues aren’t completely over. In the first act she learns that her boyfriend’s roommate Ryan (Phi Vu) is actually one of three students working at her university’s science lab. There, the students have created a device that can cause disturbances in space and time. As a result, Tree, and this time her new friends, are put into a position of having to make fixes to the space time continuum, while also dealing with a murderer on the loose.
