That duck
While it may seem old to make fun of Batman's voice, this was still a fun cartoon. I think the duck's noise was probably more incomprehensible than Batman's anyway. It was such a relief when the Joker got rid of him and (seemingly) blew him up. You can make anything funny by making it sound like a duck, specifically Donald Duck. The animation was pretty good, although some of the designs looked a little off. It was good fun to hear him ramble on at the end by placing the mouse over things.
