Finished season two and am halfway through season one... really, really enjoyed the back story provided by season two, what a world it must have been back then... i'm officially a huge fan now.
Season one, while lacking the production values (particularly the cgi) of forthcoming seasons, may be my favorite so far and it mostly has to do with Andy Whitfield... he just has a much bigger range of emotion than the new guy, he also actually looks like he could be Bulgarian/Thracian, the new guy lacks his range and looks like just another pretty boy englishman.
The fight choreography is truly incredible, some of the very best sequences you'll find anywhere... spartacus and crixxus(sp?) vs theocales was brutal or the free for all in the circle of fire at the end of season two... awesome.
But like i said in an earlier post, season three REALLY seems tamed down so far... way less gore and sex, plus this new guy simply doesnt have Whitfields gravitas, not at all, what a shame the guy died of cancer.
