The spiritual sequel to "Groundhog Day." It would be a good idea to have seen that movie first, for the very few people who haven't already. "Palm Springs" never directly refers to "Groundhog Day," but they hit the ground running, spending a lot less time laying out their repeating day situation. And at one point, Nyles (Andy Samberg) says "It's one of those infinite time loop situations you might have heard about." Nyles is stuck repeating the marriage of a friend of his girlfriend - thousands, or possibly hundreds of thousands of times. But when Sarah (Cristin Milioti) joins him in the loop, she's utterly determined to get out and shakes up his lazy attitude.

This is a really good film. It couldn't have existed without "Groundhog Day," but given that - it's just as good. The other essential viewing in this category is the spectacular "Russian Doll", but there are several others worth seeing of similar construction.

This was good enough that I watched it a second time three days later. And it's good enough that it holds up very well: things you learn later in the movie radically change the way you see things that happen early in the movie - and it's all well thought out. Highly recommended.
