An interesting third "season" comprised of 5 episodes. A few thoughts:
1. Much higher resolution: couldn't tell if that was Netflix or better video quality from the BBC. In either case, the show had much higher production values across the board.
2. Sad to see Ianto die. All of the cast (except for Gwen) bit the dust over the last 2 seasons.
3. Another deux ex machina ending. I thought they might try and find out if the drug-dealing aliens were criminals in their own society, or something mildly clever. Instead, they copped out. Oh well.
Still, enjoyable except for the ending. They tried to close out the series (but apparently they are doing yet another season?).
