Dead Leaves, Tengen Toppa Gurren Lagann Recommendations
Over-the-top action, mostly unexplainable knowledge of technology when it's really needed, and characters that are instantly lovable (Kamina from TTGL, and Retro from DL).
Both from Hiroyuki Imaishi-
-crazy over the top action
-unique art style
-fast paced, quick cuts
Although Gurren Lagann is a lot more serious than Dead Leaves, both have simple cartoonish art-style but with awesome animation. They both also have crazy, random, and sexual humor. If you enjoyed one, you'll definitely enjoy the other.
