Lisa has somehow wormed her way into my heart and is my favorite character now. I NEVER would have suspected that, but the believable, awesome shifts they have done with her character have been fantastic, as has Laura Vandervoort in portraying her. This episode when she made the right choice, I was cheering her on, and when Joshua called her "My queen," actually slightly teared up. I KNOW!! (And, yes, I'm totally shipping them now.) However, it's not just Lisa I enjoy, I've been enjoying most of the show. The twists and turns, the character motivations, the mysteries and reveals, it's been fun.
Sure, it's not perfect. There are definitely still weak points: Hello, Tyler! and I do really think it's the case of the actor, sorry to say, but that's how I see it. (Since Joshua isn't dead, can I to be haz Lisa/Joshua when they (pretty please!) kill Tyler? Blech, I know he won't die. Ugh.) Ryan can be a bit of a drag, perhaps made more obvious to me in that when he seemingly was brought back into the fold, I was pretty meh about it. And I still think that Morena Baccarin is not as nearly as good as her press would indicate, but she's not bad at all, and she definitely has her moments. And speaking of Anna, I did love what they did at the end of this episode with her. When she was crying and raging over the death of her soldier-babies, I was thinking it didn't make sense because it was such a human reaction and Anna is so not human, and then Marcus -- BAMF who is the last, I think, that will EVER have a human emotion -- pointed out that, yuppers, she was feeling that human thing. And her reaction was just to fall down to her knees crying (while Lisa smirked behind her ... because Lisa is awesome).
Of the characters, Lisa (obviously!) is my favorite, but I still love Erica, Jack, Joshua and Chad. And I'm so glad that Chad seems to be on the side of the Fifth Column now. Yay! Go Scott Wolf, I've always liked you. Also, it consistently cracks me up whenever Anna talks about Erica being her ally because it really does appear as if she totally believes that, and I love it! When that reveal comes, it will be FAN-FUCKING-TASTIC!
Being me, I have mild shipping going on, see mention above of Lisa/Joshua. I also like Erica/Jack -- yeah, yeah, he's a priest, but Elizabeth Mitchell and Joel Gretsch have chemistry. And I do think that the show expects some mild shipping there; after all, they had Hobbes flat-out call the two out on the whole Thorn Birds thing a few eipsodes back, hee!
Overall, it's just become a pulpy, fun, dramatic-verging-on-melodramatic show with some great acting, great characters, interesting arcs, and genuine awesome moments. I like!
