Ever since the 'Trinity' season, the show was crappy (seasons with Lumen and that Jesus freak Trevis were lame). But this season was amazing IMO. I hope they bring Hannah McCay back.
PS One thing didn't land for me tho, Isaak is supposed to be this Terminator-like assassin yet he's scared shitless of the two killers they send after him, but killing those two didn't even make any decent challenge in the end. That was kinda lame.
