Primeval looks to be extinct.

Despite a movie and a US remake on the cards, Primeval looks set to join the great unresolved cliffhangers of TV.

I thought the third series (the biggest, at ten episodes) was a bit shaky. Losing two of the main characters (one of them the week it got gubbed in the ratings by the Doctor Who Easter letdown) hurt, and being able to hear about 2/3 of a new character's lines in the old one's voice didn't help. Anomalies in human history appeared for the first time, which could have connected to their increasing appearance in our time and hinted at a looming total breakdown in time, but maybe that's just me reading too much into it. But they did pretty much make one of the episodes I'd have pitched to them when the series started, which was nice.

And although they appeared in what is now probably the final episode, we never did get a Raptor Versus Future Predator fight...
