If you really know The DCU you cant complain about it. I dont know why people are so negative about it. This is great movie and you should go for it. How many origin stories are really really great I guess very less and its one of them.
Guys its not a marvel movie which will make jokes its DC so you have to be serious.Now people say Batman is weird well he should be its 20 years since he is fighting crime and even robin had died. Personally I advise you to watch and judge yourself don’t listen to any critics of imdb or whatever. And yes salute to Hans music.
