After all these years I can't figure out why that movie took place during Christmas time --- maybe it's because Riggs was sad and alone after his wife died and Murtaugh was trying to cheer him up, which is a Christmas-y thing to do

It reminds me a lot of the first Rambo movie because it focused on the PTSD that a cop or soldier is going through, whereas the sequels are just corny action movies without all the psychological baggage
