I always know I watched a good movie when it can really change your mood or make you feel a certain way. While I didn't like the movie, one of the most depressing movies I've ever watched was "Requem for a Dream". Really disturbing and I've never watched it since the first time I saw it but a really powerful movie.
More recently I watched 3 Billboards Outside Ebbing Missouri, really good movie, both funny and serious at the same time. One of the best movies I've seen in a while.
Yeah Ive only seen Requiem once...and that was enough..haha. Ill have to check out the other one you mentioned!
yeah not one of my favorite movies by any means but just in terms of a movie that can move your emotions i found that one to be very powerful. definitely checkout 3 billboards
