Thanks for your suggestions guys. I have seen some of those, like Keizoku 2: Spec and Zettai Reido. They were pretty fun, especially Keizoku, loved that one.
Even though White Christmas isn't japanese, I think I'll start with that one. Looks very interesting and fits in terms of mood as it's december and all. Then I try Bloody Monday, which I've been thinking of watching for awhile.
Thanks again guys, and if people come across more stuff, feel free to tell me. :)
