Nemesis is definitely one of my all time favourite thrills. It vies with Slaine for 3rd place probably.
I like to think pretty much nothing in the Prog can touch books 1,3 and 4. (Apart from possibly Warriors Dawn, series 1 of ABC Warriors and Zenith Book 1).
I remember feeling a sense of loss at the end of Book 4. I really thought that would be it, but then they found a way to bring Torquemada back. And wasn't it great. Book 5, treads water a bit, relatively, but it all ramps up in Book 6. The scenes at the end of the world are just superb, especially the way Torquemada gets the terminators on his side again.
I just love how Bryan Talbot got expressions out of Torquemada's mask.
Possibly unfairly I liked it less after that. I think it was a combination of the different settings and different artists. Before that it had a consistent feel, now the style seemed to change radically. I wasn't a big Hickleton fan, but can absolutely see his art has merit. It then seemed a bit of a hotch-potch after that. Which I am sure is extremely unfair on the likes of David Roach. And I freely admit that in Book 10 I had yet to realise how brilliant Henry Flint was - it just seemed like some-one doing a Kev O'Neill impression.
