If you like Dragon Ball Z that much, I recommend you watch Dragon ball Kai. It's the same as DBZ, but without all the crap. Oh and, they have remastered it in HD. I also recommend the anime, Katekyo Hitman Reborn!I've Just started to watch animie's so here are my top 5:
1. Ghost In The Shell: Stand Alone Complex (2nd Gig also)
2. Deathnote
3. Code Geass
4. DragonBall Z
5. Gilgamesh
