Full Metal Alchemist:
Blue Exorcist and Arslan Senki Possibly Code Geass, but I would put it along with Death Note because of the psychological games played it in, it is still very good.
Death Note:
Monster might want to tackle this one a little later, while it's story is amazing it sometimes suffers from pacing problems. Future Diary is slightly more upbeat and twisted and there is also Ergo Proxy if you enjoy a dystopian theme.
FLCL:
GAINAX! Gunbuster, Diebuster and Tengen Toppa Gurren-Lagann are probably some of my most loved shows Over the top mecha action. Additionally there is No Game No Life which, Detroit Metal City and Kill La Kill. All somewhat different but share similarities in humor and action.
Elfen Lied & Claymore:
Hellsing Ultimate, it's a Bloody good time! Shiki as well but a little less profound. Black Lagoon, if you enjoyed Black Lagoon there is also Jormungand, it's not as action packed but still a good hard-sci series. Akama ga Kill and Garden of Sinners. Garden of Sinners is not actually a series but about 10 films that are in non-chronological order, which makes it hard to follow sometimes. Very good series, since it touches on almost everything psychological, magical and physiological. It can be watched chronologically as well.
Samurai Champloo:
I am inclined to say anything Watanabe so, Cowboy Bebop and Space Dandy! Others similar would be Darker Than BLACK and Katanagatari. Darker thab BLACK is really good but somehow they managed to create a second series which was not as good, but still worth a watch. Gangsta and Baccano! While both are centered around mobs are in different time periods. Gangsta is more modern and serious, Baccano! is 1930's with a bit of a comedic twist. If you enjoyed it you should give Durarara!! a try, same production company and writer.
Naruto, lets see...
Bleach, if you skip the fillers.
InuYasha, if you watch the final arc after completing it.
D-Gray-man, the third series has a vastly different art style and a few different voice actors. It is also currently airing, but season 1 and 2 are 103 episodes in total.
HunterXHunter, another slow starter but once the ball starts rolling it's simply and amazing experience.
Fairy Tale, not much to say here, fairly decent series.
