Mortal Kombat web series didn't suck either.
I'm... Somewhat curious about when JJ Abrams became geekdoms only acceptable filmmaker. First Star Trek... Fine. Then Star Wars... bkt dodgy to have the two biggest Sci fi universes in history being made by one guy, but everyone seemed fine with it, somehow. Now he gets arguably the biggest, most popular game franchise since Doom to play with as well? How is he going to be able to do justice to three separate Sci fi universes - each beloved by their own fans? Don't we deserve more than one voice, one creative vision in modern Sci fi? Eh, I'm sure it'll be... Passable. Acceptable. But I can't see it being great.
Oh, and let me put in a prediction right here. First movie will be Half Life, it will be about the Black Mesa event and it will be centred around Gordon Freeman. There's almost no other possibility in the studio system. Seriously, don't expect anything else until they make sure that their most popular and recognizable property sells first.
