Mediocre action movie

Rating: 4/10 (17 September 2019)

I've never been much of a batman fan, but I watched this movie because of the good reviews. What can I say? I really didn't like it.
Action scenes - no idea if they are meant to look retro or if they are just badly filmed. They didn't bring up any tension at all. I didn't feel in the movie but just left out.
Story - as lame and predictable as a superhero movie story can be.
I could just go on and on: superficial dialogs, bad costume and make-up (Joker), mediocre sound-track ... and - oh my god - the voices of both Batman and the Joker. I just waited for Batman to say "Luc, I am your father ..." with his voice modulator ...
After half of the 153 minutes I fell asleep (I really did), and that had never happened to me in an action movie. I continued the next day and hoped that at least the second half would get a little better. But no. No good story, no climax, bad action scenes if any; repeating scenes in different locations with slightly different dialogs ...
Sorry, but what are the good ratings for? It isn't a completely bad movie and I might have given 5 stars if not for the expectations after reading through other reviews. But it is far away from 9 stars.
