What worries me is that Warcraft is going to come of as
super cheesy.
I think the existing Warcraft universe fans are going to find it cringe-inducing, as the characters will not meet the personal expectations of the character they've developed in their imagination. The story is also going to be too truncated in order for it to fit into 100-180 minutes of screen time. There will be plot holes everywhere.
But the biggest problem I can see is that the Blizzard fanbase aren't going to be enough to keep this movie above water for long
Sure, the Blizzard fanbase is pretty enormous, and Blizzard have an enormous opportunity in which to advertise their game to existing Blizzard customers. But in cinema terms, it's still a complete drop in the ocean. The producers are going to have to make the movie appeal to the general public, who will have no doubt heard of World of Warcraft and so on in the media or whatnot, but have absolutely zero interest in the franchise whatsoever.
These people will probably take one look at the Warcraft movie and see it as a cheap LotR ripoff and lose all interest. It'll become wait for those "I'll just wait for Netflix" movies. About the
only way to get the genera public into cinema seats is if Warcraft manages to buck the trend and become a genuinely awesome movie in it's own right, without ever having to fall back on it's roots. And that would be a first for a video game movie.
What I imagine will happen is this: Movie finishes production and goes into limited release. Ticket sales are good for the first week, but begin to fall off drastically. Within a month the movie is on pay-per-view and not long after is streaming on Netflix, Now TV, etc.
Movie critics give Warcraft a pretty stale rating, around 55-60% on Rottentomatoes, and within a couple of years it's completely forgotten about.
However, this is still going to be a win-win for Blizzard. Even if the movie fails horribly, it's going to massively increase their brand recognition. This movie, awful or not
will give them a hell of a lot of exposure for WoW and that in turn will help to give their other games some much needed exposure too.
But I expect that Blizzard have already taken this into consideration. Even if it flops, it's going to be one hell of a commercial.
