Haven't been to the movies in a while but I wanted to see this as I like Zack Snyder (Watchmen, 300), good director. So I took the Uberwench and dragged her to the local movieporium.
It's ... OK. It looks absolutely gorgeous as you'd expect. The special effects are great, the directing is totally over the top, MTV, comic book style. Very pretty.
The script, however, is a bit limp. This is (I think) the first movie that Snyder has actually written himself, rather than adapting from a comic book. And it's a bit weak, often feeling like an excuse to string the special effects / action sequences together. But well worth watching at the cinema, it will lose a lot on a smaller screen.
