If Joker is a terrible movie then pretty much all other comic book related movies are unwatchable.
While it isn’t necessarily a “comic book movie”, my point is that it’s pretty much in my top few favorite movies to use a comic book character and depending on the genre of film I feel like watching that day, it may be my favorite.
I thought it was a perfect stand alone film though. The idea of a sequel has always only seemed like a cash grab because this was not a movie that was made with the intention of a sequel possibly happening, so I feel like it may just seem forced.
