I haven't watched nearly as much Anime as most fans of Anime but what I have watched I have enjoy. My facorite style is mostly stuff like Cowboy Bebop, Hellsing, Berserk (Original), Dragon Ball, and Trigun. Bsically any Anime with the old art style I am a huge fan of!. I'm a big fan of the Horror Genre. If anyone knows of any good "older" animes please don't hesitate to tell me! Again, my list isn't very big. There's a lot I haven't seen.
Some of my favorite Anime's are:
There may be more but that's just a basic list of ones that really stood out to me.
If anyone knows of some good horror animes, old or new, let me know!
