I think it was funny and they looked like they had fun doing it. Also it looked like it took them quite some time and they were actually profesional about it.
It was fun to watch!
Vampire Diaries+Gaga+Laughs=Perfect!
The girl does knida look like Nina and at some points she looked like Nina and Gaga... awesome.
And the boys... well I didn't think they looked like Ian and Paul at first but as I watched more they did have something...
Oh, and when they do the promo parody at the end and "Damien" has to do Ian's eye thing... well, let's just say it's not fair to ask a guy to do it. Only Ian can pull it off.
