That's a pretty spot-on review. It really is a stupid, meandering show. I feel uncomfortable just watching it at times and usually not because of the full-frontal male nudity (which does usually fit within the story, like when the gladiators are cleaning up or having gay sex), but rather the gratuitous female nudity (like random shots of women in the crowd completely topless).
If someone said it was stupid and juvenile, I couldn't argue with them.
... Still, it's kind of entertaining in the same way a five-car pileup is entertaining. You should be revolted, but you can't help but look on.
