Palm Springs Review –
There have been many media properties that have attempted to recapture the joy that was the time loop in Groundhog Day. I mean even Stargate SG1 gave it a shot. However, no one has quite gotten there. Well, today we might have a contender with Palm Springs.
So to set the scene, we open in on the day of a wedding between Tala (Camila Mendes) and Abe (Tyler Hoechlin), but our focus is not with them. Instead, it is with Nyles (Andy Samberg) the boyfriend of Misty (Meredith Hagner) one of the bridesmaids. Nyles is the type of guy that will wear a Hawaiian shirt and swim pants to distinctly not beachside wedding. But still, he saves the day when Sarah (Cristin Milioti) the Maid of Honour has to make a surprise wedding speech, and she has had too much wine. It is all going swimmingly, with Nyles and Sarah about to hook up when an arrow comes out of nowhere and a masked man Joe (J.K. Simmons) starts hunting Nyles for sport. Wounded Nyles crawls into a glowing cave, and even though he asks Sarah not to follow she does, and then they both wake up at the start yesterday again.
