THIS IS A SPOILER FREE REVIEW
I don't remember why we started watching this show. It was probably because it seems to be popular and we thought maybe there was a reason. The premise is interesting enough after all; a dark force is turning people into monsters and the Exorcists stop them.
There's a bit of mystery about where the main character comes from and what his unique role is in everything, but the reason I dropped this show is because IT NEVER GETS ANY BETTER.
Look, I gave this thing over 50 episodes to show me something. Character development. Plot development. SOMETHING. In the end, it's hard to put my finger on it, but I can say that if you watch three episodes and aren't gripped by it, you should probably drop it too. It won't get any better later.
