I think the ad gets a person's attention, but the constant repetition of it is absolutely ridiculous. I understand that they intentionally want to annoy the viewer, but it gets too annoying after you've seen the same thing 100 times.
Frankly, this ad makes me want to avoid JVC products like the plague. It doesn't explain any benefits of the product, and it is based completely around the gimmick of "this guy is really obnoxious and you're supposed to not like him". It's almost as if a group of ad executives were thinking of how advertise their camera to mac users, and just generalized the demographic as "women and gay guys".
