Watch the movie first, You will enjoy it. It's a fresh take towards the Batman franchise. Stop reading the miserable basement dwellers who are suffering from atelophobia. Reviews don't matter when it comes to entertainment.
Don't make your mind up by reading critics, who can't even hold a candle when it comes to creating the actual thing. Because it's easy to disregard something that comes from hard work. And keyboard warriors never know how to appreciate anything in their lives.
The only thing they want is to fanboy over fictional characters. And get triggered over how their Batman Waifu pillow is now ruined.
