I think it matters more about the story than anything else.
The guy who is directing it - I think it's David Bowie's son - did an excellent job with Moon but he also wrote it. I don't think he wrote the Warcraft movie.

They're aiming for a live action feel as opposed to CGI feel (or so I thought). This video does a good job explaining my current feeling on new movie releases that rely heavily on CGI:
If they can capture what that video is trying to explain it'll be fine.
If the story, plot, and acting suck though then the CG will just be icing on a shit cake.
