Re: Diona (spoilers)
I felt so sorry for her. Sold into slavery to become a displayed rape toy, only to attempt escape, be captured, and executed in the arena while her only friend watches. IMO, seeing her wait her turn while watching the other executions was a powerful scene. I could feel the anxiety crescend as the knife got closer and closer to her. The only other scene that stressed me more was when Spartacus had to execute Varro.
That execution style of ramming a sword down one's back seems incredibly painful. I'd rather just have my head lopped off.
A well-done show. I didn't think I'd like GOTA, but I enjoyed it more than the first season.
