DOOM has The Rock in it, and it created a story from a game that had none...of course it's going to suck.
Now a Halo movie could be cool, but I doubt it.
THey're also coming out with Duke Nukem the movie, again, probably will suck.
A movie I would like to be made, wouldbe The Dig...that would kick major behind
Edit:
HERE is the trailer for DOOM for those of you who haven't seen it. THey even have the chainsaw weapon. It really does look like you'll be watching someone playing the computer for gor about an hour. Yay for stupid ideas! The biggest plot point seems to be at the very beginning; that scientists finished mapping out the entire human genome. That's the only essence of plot
