To be honest If I really had to pick a character in SGU, and I was not allowed to say "none of them"...It would probably be Eli Wallace (David Blue).
He was the only character that I could say was half way entertaining.
*Edit: I should retract this statement, but he was the only one with the jokes really on the show, and sparked me to laugh a couple times. But I'm still upset with him in real life out of his character...he needs to learn to keep his mouth shut.
