Quite possibly one of the most intriguing TNA storylines ever? I think so.
Loved this from the outset. Abyss to me was just a one trick pony, put him in a feud, stick him in a hardcore environment and watch him go to extreme lengths, placing his body through fire, onto thumbtacks, into barbed wire, get back up and repeat the process again. He became stale years ago, and the truth is, the Hogan-ring angle hurt him so much a lot of people found it hard to take seriously afterwards. He'd "They" which was a gigantic disappointment and a lot of meaningless feuds, but this has made Abyss interesting and relevant again, which in itself deserves kudos.
They can play it a number of different ways, nobody can legitimately claim this is predictable because it isn't. However, I hope Joseph Park reveals himself to be Abyss, because I don't want to see the character end.
