Are we watching the same trailer cause that is in no way 'low quality' cgi. looks just like the games to me. Also you cant really judge the movie on cringeworthy jokes from the trailer's narrator.They all are indeed, but this seems to be a low-quality cgi movie combined with a video game movie.
Most video game movies are bad because the original writers/staff arent involved, and the people who make the movies dont even consult the game's developers. I'm not saying its going to be a masterpiece, I'm just saying you might be jumping the gun on calling it truly awful.
