Apocalypse Now
This felt like a very messy film and I loved it. I watched the theatrical cut which I have heard is the least messy and best for beginners so I can only imagine what the other cuts are like, which I plan on watching soon.
Edit: it's been a few days since I've watched it and it's one of those films that when you watch you can't stop thinking about for days afterwards, Im adding this to my top 4.
