I'm somewhat biased about this episode, what with being a hardcore fan of Gareth Thomas, who plays the older Ed Morgan. Nevertheless, here are my thoughts on watching it again on DVD.
( Torchwood 1.03 -- Ghost Machine )So overall -- the show has settled down into its long term pattern after the introductory episodes, with a reworking of the idea that ghosts are recorded emotions. Mostly decent script and some solid acting work, giving a lot more depth to Owen. One I'll be happy to watch again even without my fangirl reason for doing so.
