I must be the only one who hated those live-action trailers. Jason Alexander, Julia Louis-Dreyfus, and Michael Richards had already humiliated themselves in some way after "Seinfeld" got canned, and I had always hoped that Jerry would be the one to preserve his dignity, but the old trailers kinda threw that out the window.
This movie looks pretty darn good. Jerry Seinfeld's sense of humor is right up my alley, and his voice works amazingly well in animation, so I don't see how this could disappoint.
