Just watched tonight. This was pretty good. I was surprised. There probably won't be a sequel but there should be. Not at all a predictable ending.
This doesn't follow the story from the games all that closely. I think this is based on the origin story from Warcraft III when Blizzard really fleshed out the background. Either I forgot most of the story or they strayed quite a bit. The whole 1/2 orc thing made no sense (probablly just a reason to get a hot female warrior on screen), but overall I really liked it. I thought the CGI was pretty damned impressive too. Especially all those orcs. The textures of their skin and their scars
