Pixels, and why videogame-movies are bad

Firstly, Pixels might be a new low, and for two reasons: its a videogameadaptation of 30 year-old games, and it stars Adam "I dont know how to make a movie" Sandler. And I doubt its going the clever route with its action-scenes either, wich mind you, isnt that hard if you google the original AI patterns of the ghosts in Pac-Man.

But, why then is it that movies based on video-games suck? Well those directed by Uwe Boll can be explained by the film-tax in Germany. But there are others, Whats wrong with them? First theres the fact that games are an interactive medium and the core of the game cannot be transfered onto the big screen. On the other hand, the wrong games are chosen to be adapted, Doom, Need for speed and Postal dont have immersive stories, they exist for the gameplay, not to be made into movies, but I'm too late with this. So now we can conclude that the wrong games are made into movies, are things improving?

A Mass Effect movie is in develoupment, as is a Last of us. But so is a Sonic the hedgehog one.

So, thingd are improving, if not perfect yet, and the list shows both a Portal and Half Life movie, wich would be great if we had the third installment on either series.

A Zelda netflix series has been rumored about and the quality of the pokemon anime-series brings hope to that project. Heres to hoping that from now on, we get better Videogame movies!
