Happy Death Day ★★★½

Well, we all know the Groundhog Day formula.
It shook things up enough to entertain me though. The masked killer adding a bit of danger and a clear mystery to solve was good, and I like that it ties into the whole dickhead protagonist that becomes a better person over the course of the resetting day thing.
This film didn't blow my mind or anything, but it's pretty fun, and competently written.

Going in I expected this to be 2½ stars, middle of the road. I was pleasantly surprised and had a great time.
