Maybe its cause I've played the games but nothing about the trailer is all that confusing. I normally don't cry about CGI in a film, I mean if it looks decent then it doesnt take me out of the story, but the complaints I'm hearing about the film sound more like whining and crying over spilled milk.
I'm looking at this as a WC fan and the environments and settings that I spent a good couple of years in are pretty much being realized on film and that has me giddy and will let me overlook some shortcomings, even if they really arent all that glaring.
Now if the story, plot and characters all suck then i'll be upset but the trailers are just giving us a taste of the world, an idea of the conflict and thats it. Dont have enough from it, I mean it IS just a trailer, to say it'll be horrible or unimpressive.
