In the lush new Showtime drama 'The Borgias,' Jeremy Irons heads what the network smartly brands "The original crime family."

That correlation --  between the real Borgia clan of Italy and more contemporary crime families both real and fictional -- is marketing genius and extremely fitting.

The Showtime story of the Borgia climb to power begins with Rodrigo Borgia (Irons) essentially buying his way to the head of the Catholic church. The story builds slowly, with much of the first hour devoted to establishing the setting and tone of the series. Once Borgia is officially installed as Pope Alexander VI, things pick up. Because that's when all the murdering begins.

Although familiar with some of Georgia O'Keeffe's work, I don't really know much about her life.

I can't say after watching Lifetime's "Georgia O'Keeffe," (Saturday, 9 p.m.) I learned a lot more.

But it's probably not fair to expect that; this is a Lifetime movie after all. So, this portrait of the artist is told through the story of her tortured love affair with photographer Alfred Stieglitz.

Luckily, O'Keeffe is played by Joan Allen and Stieglitz is played by Jeremy Irons. Which means the acting is terrific.
