WW84 is not a very good sequel. The story is confusing and not very interesting. The decisions each character makes doesn't make sense. I enjoyed seeing Chris Pine, I feel the script did not do these actors justice. Once again Disney/Marvel beats Warner/DC.
The source material is there already, with a few tweeks and you have a respectable, decent movie. I felt it was overly "preachy"and campy. These are comic book characters not everything has to be a lecture.
Warner need good story tellers like Jon Favreau and David Filoni to make these characters and story shine. If you want to see these characters at their finest see the animated movies skip the full length movies (except Aquaman Shazam and Joker). I would not recommend this movie. Good thing I watch it on HBO. Still waiting for a really good DC movie.
