Hmmm can you guys help me choose which show to start watching. I only watch one show at a time. I am not sure which one I should start first. I will watch both  anyways but i watch at slow pace one at a time. 

Between Prison playbook and Signal 

Something to consider about Prison Playbook   - a very close friend of mine is Korean, and NEVER watches K Dramas. He RAVED about Prison Playbook, telling me how good it was and how much it reminded him of his own time in  prison in Korea. That's a pretty powerful vote for its authenticity.

Prisonplay book , lots of my friends have finished it. You should really consider watching, also if you are slow watcher then it’s good for you. On episode a day, you will definitely enjoy it.

I'll start Prison Playbook. Thanks for the replies
