Did that one already. I didn't get the hype on that one. It seemed like good bones, but not enough meat. I never really got a good reason to care about any of the characters in Kill la Kill.
Not really sure what's next.
I don't know what you've seen and what you haven't, but the short list of anime I generally give people goes something like -
Cowboy Bebop (Space opera)
Ghost in the Shell:Stand Alone Complex (Cyberpunk police)
Death Note (first season only, second season is garbage) (Supernatural vs Police)
Code Geass (Supernatural vs Imperialism with a side of Mecha)
Tengen Toppa Gurren Lagann (Ridiculous Mecha combat)
Black Lagoon (Action/Crime)
Attack on Titan (Action/End of humanity)
Samurai Champloo (Anachronistic historical fiction drama)
Big O (What if Batman was about mechs)
Another (Supernatural horror)
If you've seen all that or they don't sound like they appeal to you, you might also try
Kill la Kill (Ridiculous high school combat)
S-Cry-Ed (Rivalry, Order vs Freedom)
FLCL (Batshit acid trip)
Paranoia Agent (Supernatural vs Police)
The Melancholy of Haruhi Suzumiya (viewed in chronological order, not in broadcast order) (A bored schoolgirl unknowingly defines reality)
Trigun (Wild West on a new planet)
Toradora (High school romantic comedy)
