This is hard. I'll just pick those that left a long lasting impression on me.
1. Interstellar (I watched this one 5 times in the cinema)
2. Kingdom of Heaven
3. Call Me By Your Name
4. Joker
5. 1917
I excluded Lord of The Rings/The Hobbit, Harry Potter and Marvel movies because otherwise my entire list would be just them, and I wouldn't be able to pick just 5 anyway.
