Good God, I hate this song. But I'll try to be as unbiased as I can. The lip syncing is OK, and the art is nothing special, and there is absolutely NOTHING going on. The singers just stand there, with the very rare walking scene or screen effect. There isn't even a background. Easy stuff. It wouldn't take that long to add a background. Well anyway, it needs work.
(Sorry if I sounded like a dick.)
