The Princess Bride is of course the best movie ever made.
But there are plenty of good ones. The latest one that I really enjoyed was Shang-Chi (Marvel flick). A very fun movie. There have so few new movies the last 18 months... I am so ready for theaters to reopen.
If you really want to see a truly original film, watch "Castaway on the Moon". I am convinced that American Hollywood film makers have lost all creativity and are content to just keep remaking old movies over and over again with a modern spin. Castaway on the Moon is one of the most unique and original scripts I have seen in a long time.
I recently saw this anime, "Fireworks" (2017). The ending has some ambiguity, but it was a very interesting and very charming picture. It had some mixed reviews, but I really liked it. If you give it a chance, it's very good and will stand up to repeat viewings.
