So this is like an impromptu way of getting new ideas. Just give me a list of your top 5 favorite movies. Or more than 5, whatever.
I'll go with movies I've seen recently-ish. If I went with all-time favorites it would be a pretty predictable list.
1. Un Prophete - French prison movies. Absolutely no hollywood cliches present.
2. Primer - I've seen this 4 times and still only understand about 70% of the plot
3. In Bruges - unique kind of story line but a really enjoyed watching it
4. Porco Rosso - from Studio Ghibli
5. Nausicaa - this is from studio ghibli before they officially became studio ghibli but also a fantastic movie(released in 1986 I believe)
