The Diner Utility Closet from 11.22.63

This Hulu limited series, based on Stephen King’s novel, uses a sort of The Lion, the Witch and the Wardrobe approach. In a diner in Maine, there is a supply closet that doubles as a time portal; When you walk in, you come out in 1960, in the same spot where the diner will be built in the future. One man (James Franco) uses it to try and stop JFK’s assassination. Good luck with that.
