Many other reviews have mentioned how terrific the production was, how talented the actors were, and how erratic attention to science was throughout. I agree. I think the female lead was not particularly sparkling and, despite having survived and thrived in a horrible dystopian future, she often behaved like a spoiled teenager in interpersonal relationships.

I have one major issue with Sisyphus - TOO MANY FLASHBACKS, MANY OF WHICH ARE STUPIFYINGLY LONG. Quite a few are unnecessary and/or boring. Otherwise, it's an above average series, and you can watch it without having to warm up your thinky bits much.
