Have to agree that the three SSR adaptations are among the very best book-comic adaptations going, all the more impressive because it works so well in small chunks and keeps that weekly cliffhanger feel so vital to 2000AD. I don't love 'saves the world' as a story overall, although the mucking about in time is fun at least. The other two are all-time great capers, though. I really do love that Slippery Jim, one of the very few book series where I've read, I think, every single one, making me all the more sad we never got any more adaptations.
I also have to agree that Shakara is just a perfect example of 2000AD weirdness, and even if it doesn't maintain the wonder over all 5 books, they do all bring something new, and as a whole it's probably a 'better' comic series. Gets a bit wordy after book 1, mind. But the Flint art! So good, I think better than Carlos even, if only because there's no requirement on him to limit the imagination.
Voting with my heart on this one: Stainless Steel Rat.
And my God, if this is a taste of what Round 3 is going to be like, I'm gonna have to start taking some serious stress pills.*
