I enjoy the monty python movies, as they make me crack up every single time I watch them. I would recommend watching at least once a month if you have the time.
Off the top of my head, the best movies I've seen recently are the Hunt for the Wilderpeople, the Disaster Artist and the Big Sick.
Jaws. It was scary stuff back in the day.
Don't know why but Ronin is one that I don't mind watching But there are so much to chose or Totoro
