I like most of them, but for the one where D.W. is a superhero, I miss how the announcer says, "It's Super Sister!"
I wonder why they decided to do a variation of the swimming title card with Brain season 3, when in season 2 we learn that he's afraid of the water.
I also like the foreign version of the title card for "In My Africa." It's the scene where D.W., Cheikh, and Brain are crossing the street.
