Parts of it are great, parts are merely okay, other parts are terrible. It's a mess, unfortunately. But the villains are good. Hector Hammond is a better character in the film than he is in the comics. And Mark Strong as Sinestro is the best casting of a DC villain ever. Sinestro is my favourite DC villain, and Strong just completely embodied the character. I would forgive all the failings of the film if it meant we got a sequel where his Sinestro was a bigger focus. He was perfect.
