The only bad thing I can think of is that the second season only has 10 episodes and it's already halfway through! Other than that, I can do nothing but applaud the writers, who truly surprise me with every episode, the cast for bringing the characters to life (especially Liam McIntyre, who took over the lead role after Andy Whitfield's death and who is doing a spectacular job!) and the crew for delivering a great message; I was never a fan of green screens and CGI, but I think that by now the show's team has mastered the technique, and the backgrounds I think are incredible. There are coupon codes for Target available if you're looking to buy Spartacus on DVD or Blu-Ray.
Here are a few of my favorite stills from the new season:
