I'd definitely watch another limited-run series like this.
Me, too! Some of the fun is knowing there will be answers at the end of the season.
I like the idea of Henry being Wakefield's accomplice for his own reasons. He's the reason Abby came back to the island, after all, which she refused to do for so long and presumably is what Wakefield wanted.
Though I would also be happy if blond-guy-who-isn't-Cal was a killer, just because his little speech about needing to open up to people more was so freaking cheesy, it would be great if that was all part of an act.
