Broad humor was not the SG-1 style in the beginning and I'm thinking that's a good thing because they really aren't very good at it. Vala is often played for broad humor (uh, no pun intended) so she sticks out like a sore thumb. It's sad on many levels, not the least of which is that CB is freakin' talented that she CAN do the broad humor and sell it but it's wasted because nobody else can play.

Daniel is too serious and grimace-y in the face of Vala's provocation. Poor Sam apparently had 98% of her sense of humor removed on birth (except when she's teasing Cam about losing his pants -- I LOVED that). Strangely, her over the top character seems to work well with Teal'c's stoicism, but that's because he's being her straight man and we're used to seeing minimal reaction from Teal'c to highly disturbing events.
