never have I left any reviews so I applaud you to coming to the conclusion that my reviews and voice on movies are not valid due to lack of reviews, but If you had made it this far thank you.
The movie was poorly written and had no intention of being a movie about the joker but being a starting point to set up batman.
the laugh ( super iconic ) is just thrown in as a medical condition too give it justice for being used in unnecessary parts of the movie, and in my opinion ruins the whole vibe of the joker
the movie had scenes that would benefit if they were not even there, like the bruce Wayne behind the gate scene was totally useless and built nothing for the character.
overall, this whole movie was a failure to make money off heath's performance of the real joker. good try but the movie doesn't live up to anything that the joker is or was.
