No one said Marshall as their favorite character? I voted for the lovable geek. Granted he isn't the sexiest or the star by any means, but the show wouldn't have HALF the entertainment value if Marshall wasn't there.
I think Sydney's character lately is a bit flakey so I can't say I am enjoying her character lately. If I were to pick my next favorite character without basing on sex appeal it would be Jack, then Sloane, then Sark, Lauren, Sydney then Vaughn.
I think Jack is great at being spy daddy. For the most part he is cool and collected. I love it!
