After watching this I can honestly say I feel a little better about this movie considering one of them is a huge Warcraft fan and the other isn't but they both liked the film (plus I trust their reviews, they're generally more level headed then most other reviewers).
Heh, I honestly didn't know most of those names I mentioned until I played WoW (I hardly remember playing the original Warcraft outside of Medivh's death and a few other points of interest, everything I know about it now was from reading up on it). WoW introduced me to the overarching plot that connected the first three games and got me extremely interested in what caused the events that lead to WoW's original starting point (4 years after the end of The Frozen Throne). I remembered the majority of WC2 from having played the hell out of it on my original Playstation (back when they used to port RTS games onto consoles, wasn't the greatest port but the game was still fun as hell) and WC3 was still fresh in my memory since I had only recently finished another play through a month or two before WoW's release. It's funny how a game that spent more time rewriting this established lore made me and many other players go seek out and read all the established lore (plus the game itself contains a lot of this lore if you know where to look).
