I'm guessing maybe that so many video game movies turn out pretty rough?
Not that it's always the case. There's at least a handful of decent ones out there
Silent Hill was pretty solid in my opinion as an example! I can sort of understand the sentiment though. I hope it turns out well.
I think I'd like to see an indie director with a smaller budget and a ton of drive take on an adaptation of a game someday to see what happens when a video game movie is made by someone who isn't beholden to execs/shareholders who don't try to twist the film into something generic or untrue to the source material.
Maybe even an adaptation of an indie game like Limbo would be cool!
