I've been watching the Dollhouse - the new show by Joss Whedon. It's good. It stars Eliza Dushku who plays a blank woman who gets a new personality on every show.
It kind of follows the same model as Quantum Leap or Sliders but Joss Whedon has put his mark on the genre.
There is a lot intrigue but already the writers are going to the same old TV show plotlines that other cop/adventure shows follow. For example the last show took place at a Branch Dividian type cult compound.
As much as I like the show, I don't think it's going to live past one season.
