Well, if there can be a series of five (with more on the way) Resident Evil movies that have little to do with the games, I guess there is room for a Warcraft series that goes the opposite route and drowns viewers in the lore from the games. *shrug* Joe and his buddies seemed to like it well enough, for what it's worth.
As for me, I haven't been interested in Warcraft since it became a MMO game, so I have no real interest in this movie either. (Also, I'm still disappointed that Warcraft Adventures was cancelled almost two decades ago. ¬_¬)
But then, of course, I haven't been interested in anything Blizzard at all ever since Diablo III.
