I don't feel like doing a top 5 martial arts movies, like the thread title suggests, but here's just a general top 5
Not in any order, but numbered for the sake of numbering.
1. American History X
2. Shawshank Redemption
3. Billy Madison
4. Inglourious Basterds/Pulp Fiction (Lumped together since they're both Quentin Tarantino)
5. First Blood (Rambo)
