If anyone had told me this was similar to Excel Saga, I never would have bothered checking it out. There's no denying that FLCL is absolutely out of its mind insane, but it has a certain... something... that Excel lacked. Edge? Wit? Conspiritoriality? (I don't think that's an actual word...) Heart? Charisma? All of the above? Whereas Excel instantly grated on my nerves and annoyed the hell out of me, FLCL kept me amused and interested and entertained for the duration.
