Just watched The Last Outpost (I'm planning to watch just one episode a day). Another great episode that looks and sounds superb. I love how the sound of Portal's energyfield travels through all the speakers. The 7.1 mixes really do add something (when they're authored correctly). Great job.
Yeah I'm doing the same one-a-day thing too.
One other thing I really liked in Last Outpost was the conference room scene, where they attempted to show the light from the sun moving across the room over time.
It's a shame they didn't continue to do that, because it really gave a sense that this was a real ship in space and not just a studio set.
