Marco or Sidwell. They are not my favorites but I don't hate them.
I don't mind Marco. They haven't given him a ton to do but I see a lot of potential. Sidwell on the other hand, I just don't believe him as the big bad. I don't find him menacing, cool, or funny. The scenes with Alexis were so weird. At one point, he even rolled his eyes. I need him to take a more heavy hand and be intimidating. He's just there for me. Peter was too cartoonish. Cyrus was cool, menacing, and lethal. Victor was menacing, cutthroat, and funny.
I swim in the same direction on Natalia however... she was awful... glad she is gone!
TPTB are to blame for that. Not sure if you read her exit interview. They screwed the pooch on her character.
