I don't really get this practice over at WB. With a couple of exceptions, Disney ensures there's only one voice for Mickey, Minnie, Donald, Goofy, etc. across every possible platform. Give the LT some consistent voice actors too.
I've watched the first two so far. The Pinky and the Brain segments have gotten the most laughs from me.
And of interest, the musical segment in Episode 2 has cameos from Babs and Buster, and some of the Loonatics Unleashed gang.
