What's your Favourite movie that's never anyone else's?

Watched Edge of tomorrow the other night one of my favourite films and it's a great film but not necessarily an oscar worthy interstellar inception kind of film.

So was wondering what's other people's similar films that are one of their favourites but either less popular or just not as highly ranked as others.

Also would take any suggestions. Cancelled netflix cause it's a scam so looking for direction suggestions
