Let's see...
Movies:
Akira - One of the most impressive animations of all time, i also recommend the manga, which is much better, but the movie is very good too.
Ghost in the Shell - No need to tell about this one.
Errr...Ghost in the Shell 2? - Kinda confusing but is good, not as good as the first one but is enjoyable enough.
Series:
Dragon Ball (all, except GT and the Buu saga)- I not like very long animes, but Dragon Ball kick ass.
Yu Yu Hakusho - Same as Dragon Ball, long but is awesome.
Cowboy Bepop - Best anime ever... In my opinion of course.
Hokuto no Ken - If you don't watch that one then you are already dead...
Hellsing Ultimate - Proof that not all vampires those day are gay. Very good.
Don't Recommend:
Evangelion - No, No, I not trying to make confusion here... But i can't recommend that, a anime where the main problem is the main protagonist it means there is something very wrong with it. There are some grown in him during the series, but even in the end he is still a wining little *****.
Elfen Lied - Good, i would recommend, but i recommend the manga instead, for release the manga there's a fucking closure. I can't recommend something that simple end like that, is frustanting.
Berserker - Same as Elfen Lied, is pretty good but there is no end and but read the manga that you win more. I read that is gonna be continued, but i would not depent on that.
High School of the Dead - I know there is people who liked... but... Dude... Like...Its too erotic...I know that people who kinda like that stuff...but...you weird...You should feel shame of yourself... If you really wanna watch them make sure that you are alone.
