I loved the concept of the video. I wish people would stop saying Katy copied Gaga; I love both, but realize: this song is about aliens. Katy is going to dress like an alien.
WHich, by the way, was quite amazing. I loved the outfits she chose. However, I could have gone for some choreography from her part. I thought that would do some justice for the song's amazing beat.
Kanye shouldn't have been in it; however, he is bearable. I do prefer the Katy only version though. All in all, great show by Katy. WHile not necessarily up to par with the hype it generated, it doesn't disappoint
