I haven't seen the movie yet, but in a similar vein I watched Twisted Metal recently, and it's... actually good, somehow? Much better than it would have been following any of the games' stories, or even a mash-up of them.
They've clearly used the games for humor, visuals, characters, and Easter eggs for the fans, but they somehow made something better than the sum of it's parts, and it should be looked at as a great example for other adaptations, especially action comedies.
