Query: New Characters; Fresh Humor

I was honestly skeptical at first about the switch-over of characters in this season of Stargate, which is my favorite show. But after buying it and watching, I am hooked. Mitchell is witty and spastic and Vala is just plain troublesome fun. I highly recommend it to any fans of Stargate SG-1, and also to people who haven't been into the show before and would likely find something new and likeable in the facelift the show has received for it's 9th and 10th seasons.
