They managed to be cliche (bringing Owen back) and uncliche (hes still dead, just moving around) at the same time.
The episode is a bit bipolar, you have Own moping around because he cant get it up (no blood or heartbeat (makes you wonder how Spike and Angel managed that trick)), cant drink without having to stand on his head to let it out (no digestive system), cant sleep, but can still fart, although not volunatarly.
And once again the supersecret torchwood has codewords that ever police station and hospital nurse will know and recognise their authority.
Nice cameo from the black smoke monster from lost, shame the skeleton looked a bit pants when it was out in teh open.
And Own has 30 years, or 30 minutes to live, but is still dead, although I imagine he will be back to full life next week in time for Marthas last episode.
