Same crazy mix of parody-comedy action with nevertheless a strong and complicated story. "Gurren" originates from super robot mecha animes, "Edo Rocket" from harem-type with this special girl that just falls on protagonist's head=) They both exploit some common themes but do it in a bit unexpected fashion.
