I am thoroughly enthralled by what this show has to offer. I had the benefit of catching a repeat of the first few episodes back to back, and I am hooked beyond belief.
What stuns me is that everything seems to have a purpose behind it. At first, it appears to be an adventure that is random for the sake of being random. However, as the show unravels, there is a strange sense of mystery that would make Sir Arthur Conan Doyle proud. Shows like Lost have failed to grab my attention simply because I felt as if the writers were trying to make a 5-show plot thread last for fifty.
To be honest, I don't believe I've been this hooked on a show since Firefly. The main character could have easily been played by Nathan Fillion to the same effect of character. I hesitate to make any more comparisons; I'd hate for people to think this show is a hybrid of this or that. Something about it makes it completely unique.
I'm looking forward to where this show goes. I actually believe that history will remember this show as a benchmark for things to come.
