Yes and also no.
The miniseries that launched the series? Absolutely worth it, but Lucy Lawless isn't in it.
She comes in around the end of season 2. Annnnnnd... eh.
She's fantastic, but what she is given to work with isn't great.
I don't want to give spoilers, but she essentially breaks down over time. A true follower of the faith to someone screwed over by prophesy.
If you do any web searches at all about her character, spoilers will pop like a soap bubble.
