I really did love most of the 2017 Wonder Woman film, everything except the useless CGI battle with the useless villain at the end. The no man's land sequence alone makes it one of the great super hero movies. This sequel, sadly comes nowhere near the first movie. At 2 ½ hours it is an hour overlong and while all the performances are good, the motivations of the characters, especially the villains are muddy at best and unconvincing at worst. There is simply too little Wonder Woman in it as well. I don't count the opening Diana as a child warrior sequences as seeing Wonder Woman. They have little to do with the plot and I swear it seemed to go on for days to make a point that could have been madd before the credits started. The weird return of Steve Trevor makes little sense... there is a magic element to the plot that takes away from the depth the first story had by being set in WW1. The whole thing reads like a mediocre TV episode. That is not to say there is no fun in watching it, there is some of that but it drags out everything from the action shots to the poignant moments. Despite making an effort to set it in the 80s, it really could have happened at any time, including yesterday. The 80s conceit is simply to avoid conflicts in the DC Universe timeline and doesn't add anything.
I would not spend too much money on seeing this and was glad I didn't have to. I haven't given up on Patty Jenkins, I think she has more awesome Wonder Woman ideas in her but I will be much more cautious in my enthusiasm for a third film.
