Here's one:
Mutant Chronicles
What an unfortunate name! It's got a good cast of recognizable people who, I thought, really pulled it off with great performances. Thomas Jane and Ron Perlman head it up, but John Malkovich and Sean Pertwee (Father in Equilibrium) also make appearances.
It's one of those AAA efforts but in the B movie genre. However, that makes it better than many big budget movies.

The basic plot is pretty much Halo/Gears of War type stuff and nothing too new. However, what's cool about the movie is the setting and style, which gives a sense of an alternate history story. The movie starts out and it's pretty timeless. There's a war going on and you can't tell if it's WWI, WWII, or set in the future. There's a year given, it's no mystery, but the way they handle the setting and the mixture of technology is very cool. Kind of a steampunk look about much of it. As the story goes on you see less and less of this as the situation develops, but it's a nice treatment.
This was on Sci Fi channel a while back but I missed it (the preview commercials looked good). I saw it on Netflix and it's on Watch it Now. If you have a 360, it's even in HD. Very good looking movie.
