Happy Death Day 2U is a satire of slasher movies. If you saw the first movie (which I reviewed here), you’ll get some of the references, but it’s fine to watch as a standalone.
Tree (Jessica Rothe), the main character, had the misfortune of being targeted by a serial killer. Every time she died, she woke up on the same morning, to relive that day and get killed again.
But this time around she notices some details are different, like someone not walking into a room. Then she notices a lot of things are different, including who was in on the serial killings. But why? She discovers a few lab rats on her campus have bungled a quantum time machine, which has shifted her to an alternate universe.
So this time around, it’s not just a matter of screaming and running around to stop the serial killer to break the time loop. It’s a sideways hot mess as they guess their way around and through the multiverse.
The trailer showed too much, so here is an interview with Jessica Rothe with the quantum machine in the background.
Happy Death Day 2U is one of those rare comedy sequels that is funnier than the original. It’s especially hilarious to see how screaming mad Tree is when she finds herself in the loop—again. They changed the genre so that it is not just horror and comedy, but also science fiction. They not only play around with the wacky alternate reality, but it increases the tension with each attempt to solve the quantum dilemma.
The first movie rested entirely on Jessica Rothe’s shoulders. But now there are multiple people trying to figure out what is going on, each contributing to the humor.
Do not make the mistake of walking out when the credits roll. There is a remarkably long set of scenes after them, ala the Marvel Universe.
As a caution, Tree decided to kill herself a few times rather than getting murdered. Her suicides are funny, but if you or someone you know should not watch that sort of thing, be cautious.
