Let me start by saying, if you haven't watched OiTNB, you should. Largely female cast, excellent writing, witty, gritty and utterly moreish - I watched the whole series in 2 days (I sound like I should be writing a bad TV column in a trashy paper). Seriously though, everyone should be watching this for the well written female characters alone. It's a Netflix series so it's only shown online (I don't know of any plans to show it on TV but hopefully it will be in future). This is a show you will not regret watching, I promise.
