Oh believe me there is a lot of flesh. In the first 10 mins or so you see just about everything you could (apart from the one thing) of Christian Cooke (i'm sure you can guess the bit you don't see

)
But later, you see a fully naked dead body (including the bit you don't see of CC)
You also get two nearly naked lads later in the show (ok they are not nearly as good as CC, but some people may like them)
Regarding women, not so much yet, some very good looking women, but not so much flesh except in the last part.
Regarding the actual drama, i enjoyed the first ep, a lot of mystery and drama, but also a lot of less serious stuff. I think many people will enjoy it, and even if you don't enjoy the first ep that much, you should watch the second ep.
In the preview for the second ep, it looks amazing, so much going on, much darker, more secrets. I can't wait for it.
Well done ITV on what so far seems like a brilliant drama.
