Huge movie enthusiast here! Well, I actually used to hate watching movies until last summer, but then I somehow got into it - I never liked badass-action-movies and comedies and never bothered to see animations, so I guess that's why I'd generally fail to find a suitable one to watch in theaters, but as I started to grow my own taste I got into cinema more and more. The last one I watched was Miss .45, I watched it last night and I found it to be kind of dull but it still had some pretty good scenes as well.
However, as for my favorites, while my favorite director would definitely be Stanley Kubrick -especially because of the revolutionary 2001: A Space Odyssey -, I can't really name a certain favorite movie. The most emotionally striking one was Tarsem Singh's "The Fall" for me, it is the first ever movie to make me cry - and the only one so far. I was really amazed by the plot, acting, and when you add up delightfully amazing pictures to that mixture, the resulting movie would be absolutely fascinating, such as The Fall. If you haven't seen it, I'd strongly suggest you to do so, even if you don't like dramas (I didn't either but this one ended up being one of my absolute favorites).
Another favorite of mine is Terry Gilliam's Brazil, I was utterly amazed by pretty much everything in the movie, and especially the intense final scenes and the last minute plot twist left me in amaze, I remember just staring at walls after watching it. It was, again, visually satisfying, but it had a lot more iconic scenes than The Fall - while that one was generally based on beautiful scenery, Gİlliam managed to combine that beauty with important aspects of the plot - and that's why I ended up taking almost 30 screenshots from the movie

It's also a must-see in my opinion.
The last one I'm going to talk about is Lawrence of Arabia. It is the longest movie I've ever seen but I didn't feel the least bit of boredom while watching it. Every scene of the movie was like a painting, the acting of Peter O'Toole as T. E. Lawrence was extremely realistic, basically everything about this movie was fantastic. After watching this I could never get the line "No, Dryden, it's going to be fun" out of my head. I couldn't believe the movie was made back in 1962 when I saw how good it was even compared to most of the movies today, and it still remains of one of the most amazing cinematographic experiences I've ever had. As someone who's never been into war movies, this one was really exceptional to me. And FYI, the movie had no woman in the cast, so it's the longest movie with no woman acting in it so far. And every movement in the movie is from right to left, because the director wanted to imply that the movie was actually a huge journey.
I do have a lot more to talk about but I don't want to bore any of you guys and I also have a debate match to study for. So yeah, I hope that you enjoy these movies as much as I do!
