To be fair, there were quite a few good things in this episode. Jake grew on me and I liked "Mrs Moore" from the start - I wondered whether the name "Angela Price" was supposed to be significant? kharin commented that it would be interesting to re-introduce the character in our universe; it was certainly disappointing that she didn't survive the episode. I wonder whether she might appear again later in the season, or maybe even in Torchwood. I liked the way neither of Rose's "parents" cared for her in the parallel universe. The Mickey/Ricky thing was clever and resolved itself superficially, though on nwhyte's journal, various people have observed that the fate of Ricky's grandmother remains uncertain.
But on the negative side, magic_wanderer is quite correct that it was a collection of set-pieces. The storyline doesn't really hold up to any deeper inspection. The resolution of the cliff-hanger was clunky, to say the least; Lumic was a rather wooden villain - in fact quite a bit of the acting and dialogue was wooden - and why did Lumic, as the post-upgrade Cyber Leader, need that Jim'll Fix It Cyber Sofa?
In Confidential David Tennant marvelled at the Mickey "story arc", which beggars belief. I've never been a great fan of the Tyler-family-RTD-soap style, but it just doesn't work for me that Mickey finally joins the TARDIS crew, only to leave a couple of stories later - and in a place where they will never see him, and he will never see them, again. The reasons for Mickey leaving seem fair enough, perhaps it's a question of timing. I'm tiring of Rose quite quickly now; as a character her development seems to be mostly negative, whilst Tennant is getting quite a lot more to do than Eccleston had.
And it's another return to Earth next week. We were promised "alien worlds" in this season, but I don't think that has been properly realised yet.
