I think it's best to look at it with caution at best for any game adaption.
Video game adaptions have just never done all that well. I don't think I could reserve judgement completely given the material and where it's coming from. Given blizzards own statement, WOw has always had a silly aspect to it. Does that translate into the movie too? Cause I hope not. What a quick death that would cause in my eyes.
However, Superhero movies at least have been doing well since the original superman with Reeves and Batman with Micheal Keeton and those are pretty far back now. Some better than others but game adaptions rarely do all that well and rarely, if ever leave you wanting more.
