Suicide Squad.
My dad is a huge DC fan and rented it on DVD. I don’t know why I sat through it. Also, did the Joker seem entirely irrelevant to the plot and only there because Harley was in it?
Not only was he irrelevant to the plot, but he was the worst thing in that movie, and it was full of bad things. He wasn’t remotely threatening, he was annoying. He wasn’t The Joker, he was a stoner with a cold.
