Why so different from the first one?
It’s basically a reboot instead of a sequel, nothing from the first film is referenced or continued, the entire tone is different, the first movie was one of the highest grossing movies of all time but this didn’t built on it in anyway.
It’s not a bad film but it’s not really a Batman film, it’s a Tim Burton story with Batman added in here and there.
Should have binned him off and got Alex Proyas (The Crow and Dark City) to make a proper sequel to the original.
