The one line he had in this preview, he was just excited. I don't know about you, but I've seen people that excited before... it's not exactly out of the ordinary unless you're living in a retirement home.
Considering it's part of his enthusiastic character and he just traveled across the galaxy to discover what could possibly relate to the creation of mankind, and he's just about to enter the home of these 'gods', you'd think some excitement would be warranted and not, you know, hammy?
But yeah, I'll just put him in the pile with Lindelof of random things to hate.
