I'm really not a big fan of the muppet-style ghosts... I prefer when they go for something more horror-based like the librarian in the opening of the first movie. Also, the Judge's performance in that scene is atrocious. And from a story perspective... it just makes no sense why the Ghostbusters would be in trouble when hundreds of thousands of people saw a giant marshmallow man walking through downtown New York.
and also... why was Winston left out of this scene?! They show him at the very beginning of the trial, but then he just disappears!
