Just watched this on Netflix last night:
Good action flick with an intense tempo. Plot is thin but not non-existent as some critics have claimed, and I'd say the lack of a good plot never got in the way of me enjoying the show and the action anyway.
The CGI & SFX are supposed to be the highlight of the film, and they do not disappoint. To my untrained eye, they are every bit as good as the best of what Hollywood has to offer, bearing in mind that the movie is about a gloomy and gritty post-apocalyptic world, instead of something beautiful and pristine.
