Yes, Disturbia is a random, pointless, boring video.
It is only Rihanna in 20 different outfits without a plot. The feathers outfit in Disturbia is as random as the silver paint scene in Umbrella. Rihanna is definitely no visual artist. Sure, Rihanna fans are impressed with those cheap tricks and think is the best ever but it really isn't.
Womanizer is a mini-movie kind of video. It is fun, tongue-in-cheek, and fast. You don't want it to end.
