It follows the new Joker take on the Gotham universe.
They give us a different batman, a batman that's purely driven by revenge "I'm vengeance" with a different approach to his origin story although the morals are there. No killing, no guns and a sense of honour.
Batman grows throughout the movie, finding constructive purpose and molding to what the city needs him to be.
The movie itself is well made, a noir take on a rotten city with a different batman with room to grow.
This said, the movie is slow, batman plays his part as a pawn in the Riddler's plan and doesn't solve or stop anything which is strange given the detective facet they show. Riddler's plan goes through with a forced ending producing Gotham's saviour which doesn't seem that well thought. The idea is there, the people start to believe and follow batman, their saviour, but considering batman didn't stop any of the Riddler's plan, it's a bit of a miss.
Three Riddler turns out great, if being a sociopath is what's intended.
The suit is cool and we are presented with an inventive but not futuristic batman. In every gun fight I wondered how the suit was so bullet proof but light and manoeuvrable enough for him to move and fight, jump, climb, etc. He builds the bat mobile and the bike and they are similar to regular vehicles, just enhanced. The car chase is brilliant and after penguins car gets turned over, the cinematography is excellent.
In the end, I believe we were spoiled by Bale's batman, which had the wits, the tools, the toys and gadgets that amount to a brilliant batman, along with excellent villains, something this one isn't after the first movie.
