I love it when the woman has skilz
What turns me off is when the guy doesn't... but still insists on running his mouth. I particularly dislike it when the guys keep asking the girls stupid questions that they're not even sure they're supposed to be answering. Or when the cameraman, outside the action, is giving directions you can hear. To me that just makes it look like no one there had a clue.
Oh yeah, another thing that's terrible... dubbing in sound later, with people making noises that are not quite synched to the action (and often with voices that don't quite match the performer either).
