Reviews are that you have to have followed the game a bit to fully understand the story events (which actully do follow the game), but every review has said beautiful work on the CGI. The CGI is supposedly gorgeous. I don't follow the games but was a fan of the previous two films (and purchased both) just for the quality of the work.

The dust settled, thinking "what a fine home, at least for now" not realizing that doom would soon be coming in the form of a vacuum cleaner.
