The Cage

I thought I'd seen a thread on this drama somewhere but I can't find it, so I apologise if I'm repeating what has already been said.
We watched it all and have finished it, so no spoilers for anyone, BUT I would be interested to hear if anyone thinks it could return , we think there could be more milage in the story.
We really enjoyed it and Sheridan Smith is great, but this time th accolades really must go to Michael Socha who played such a vulnerable character, you had to love him !
