Wow, I was wondering why his character suddenly changed between season 1 and season 2. I didn't know that he died. He did a great job in the blood & sand season 1. I'm sorry to hear that he died, way too young. He did a very good acting job on the show.
If you like season 1 you'll like season 2, vengeance ... this season is about their breakout from from the dominus and the creation of a guerrilla army. I won't mention any specifics (if you're going to see it), but many of the main characters die. You'll have to watch to see which ones: the title "vengeance" gives a very good hint. I like Andy's version of Spartacus better, but the new guy does a good job too, no complaints on my part. I've heard that season 3 is supposed to be the last, which is the war vs Rome, starts this January.
