This was actually a surprisingly good episode and is really split into two. First of all we have the minor threat (if it can be called that) of a massive mammoth on the loose on the M25, and with the use of effects and camera techniques all in all this makes for a pretty impressive set piece (with a little bit of a homage to Jurassic Park thrown in). The only complaint is that the mammoth they encounter just happens to be the non-woolly kind, but knowing a thing or two about computers and the difficulty in rendering hair or fur, I can see the meeting with the techie guys and producers. Cue a heated argument about budgets, time and not having a server farm to do all those follicle calculations and “could we look though a few dinosaur book to find a non-woolly mammoth” conversations going on. So with Lester showing he knows one end of a machine gun from another, and everyone realising he isn’t a baddie after all, Leek’s plan is uncovered and even a well placed bomb cannot stop Cutter tracking him down. It’s just s pity that Leek has so many armed guards to help him out in the finale. We are left with a big ‘to be continued’ for next week, as its revealed that the evil Helen and Leek have been gathering all the dinosaurs from the series together in one place for a purpose that so far is unknown (it’s bound to be evil). And from the preview of next week they also have a legion of mind-controlled ‘Future Predators’ at their disposal. It looks like that the series pay off will be impressive, and even though some of the CG creature creations are a bit ropey, it’s still impressive to see them all up on screen ready for a prehistoric showdown on Saturday.
