Actress was beautiful, effects looked nice, score was appropriate, but I have 1 serious beef with this.... Why are there human guards chasing her?
I'm not sure the director "gets" Portal. This would be just as bad as the movie version of DOOM since they both appear to stray far from the game story. The game is suspenseful and about strategy. The only forgiveness here is that I could possibly see adding in humans much later in the plot, and perhaps he didn't have enough time to strike the puzzle feel of Portal.
She really should have ended up in an empty hallway with a robot arm throwing in her food.
