I played Warcraft I before Warcraft II was released; you can call me a Warcraft fan. I watched the movie. My review: everyone who knows and likes the Warcraft universe should go and watch the movie. Despite some small lore alterations/discrepancies, the movie is great for its intended target audience, the Warcraft fans. It will definitely have a cult following, no doubt about that.
