So much good suggestions already. I don't recommend people to watch books turned into movie as they'll ruin your perception. Go with the book first and see your imagination into life through movie.
I'll add some that has more meaning to them than they look.
12 Angry men
The Shawshank Redemption
forrest gump
La la land
The movies that you loved reflect your ages mate,like me i love Forest Gump one of the oldest movie that i never stop watching until now,together with "Silence of the Lamb"
I've seen a lot of movies even i like watching movies. If you suggest some movies i'll tell you to watch these movies...
1.Parasite (2019 already received an oscar)
2.Captain Marvel (2019)
