Resident Evil: Extinction
The plot: The T Virus has escaped and now it's the end of the world - zombies have taken over the planet, the whole world has been turned into desert and the only survivors are either people on the run, or Umbrella executives sat in their underground labs.The good: It's never a bad thing to see Milla Jovovich's face.
The bad: All you really get to see is Milla Jovovich's face. Also not a great deal happens.
Conclusion: If you like the franchise, it is an OK sequel, otherwise it's a pretty poor effort. Literally, nothing happens.
