To be honest, I don't see what's there to mess up. It's just a movie - I'm sure it's not going to be extremely based on anything. If it were, then what is the point of the movie to begin with? Why make a movie that is exactly like the games, or tells the same story? I don't know about you, but I'd be happy if they make something that's a new take on Devil May Cry. Just like I wouldn't want the X-Men movies to tell exactly the same story already told in the comics.
And even if it were *based on* one of the games (DMC or DmC), there's nothing to mess up. The games have nothing to do with a future movie. They are not canonically linked; the movie won't have any effect on the games, right? They can do with the movie whatever they want. If they mess it up, that's a shame - we'd have one more crappy movie based on a video game - but it's not going to sour the games for me. Why would it?
