Name One Way You'd Change This Film

Make Batman an intelligent detective.

Remove all the penguins.

Replace Burton.

The one part that just goes a little too far for me is when baby Oswald eats the cat. I don't know why, I personally don't like cats and am normally not bothered by depictions of animal deaths in movies like some people. Something about is just too extreme for me even in this movie.
Part of it could be I grew up watching our recorded off TV version which cut that part (along with a LOT of little moments throughout the movie) so the regular uncut version of the movie feels like a special edition.
