I thought it was decent.
There were some fairly good action sequences and the scenery was good where they Amazon women resided.
However like most super hero origin stories it took too long to get to the action part of the story.
Another slight issue I had was they let her naiveté about the world run a little long as well. Initially it was played for some minor laughs but after a while it got old.
Overall for an origin movie it wasn't bad. I'd give it a 7 out of 10.
