I started this late because frankly... I didn't realize it existed. The story is quite unique and I'm here for it. People should be talking about this more and watching it more. The acting is too notch and the casting was superb.
The younger vs older casting was done so well. I can't praise it enough.

It is a little slow to start, but it gets really interesting the more you learn their back stories, epsecially around episode 4 when one of my favorites is introduced. Give it a chance! You might end up really liking it!
