Do You Leave Dialogue On or Off In-Game?

Can't remember if the option to turn it off is given from the outset, but regardless.

Given that the dialogue rarely detracts from game play (if anything it enhances it) and really the game is partially made by the witty and generally light hearted banter between Pit and his friends/foes, I never found a need to turn it off. I admit sometimes I looked at the bottom screen just for character expressions even if I was getting shot at from many directions. :p
