"WHAT THE HELL IS GOING ON?!" is basically what I thought, for at least half of this one. As it turns out, the plot is actually fairly simple and a nice twist on the standard serial killer story: the killer, Lukesh, finds his prey in a parallel universe, avoiding capture in his own. During a stakeout in one universe, Lukesh kills Reyes, and shoots Doggett, paralysing him, after he has followed him into the *other* universe. BUT, and this is where it gets tricky, when Doggett A steps through into universe B, Doggett B disappears from Reyes B's flat after she gets the call about Doggett A's shooting.

Confused? So was I. And, to be honest, I still am.

The great thing about 4-D is that, for once, as the viewer, you don't have that privileged position you often have (and seemed to get more and more throughout the last few series) of knowing much more than the "hero". The teaser and the scenes of Lukesh's home life poses more questions than they answer, although the link between Lukesh's nagging mother and his penchant for cutting out women's tongues is a nice if disturbing touch.

The bad thing, to me at least, is that it really pushes the credibility of Reyes' astute intuition. Do we honestly believe that she just *guesses* this stuff about parallel universes? I really struggle to, and it feels like a bit of a cheat to have people "just knowing" anything, particularly when it's the kind of idea you'd dismiss offhand if you even had it in the first place!

But yeah, the big problem here is: how the hell does this ending work? The whole story happens, and then, for some reason, Reyes B is not only back in her flat, but no time appears to have passed. Why? Who knows?

It doesn't actually matter though. It's good fun while it lasts, and you'll stay tuned in if only to figure out how they're going to finish this. I may be jaded and cynical, but I can hardly have been the only one thinking that a show wouldn't kill off two of its characters in the first five minutes of the fourth episode of a new series. So the teaser is less about me wondering whether they'll survive, but how.
