I just hate the stupid animations for the vault boy. I don't know how they managed it, but they actually lost all the style of the initial vault boy images. Probably, bad art direction is to blame. I don't know, but it just feels wrong. Just look at how the vault boy is animated, for example, in the Fallout 2 intro, and compare to the animations in this perks chart and recent SPECIAL cartoons.
The new ones are just over the top. Probably, they tried to do them as funny as possible, and we all know that Bethesda's perfect sense of humor.
When I see them I see the scene in South Park where Geoge Lucas rapes Indiana Jones, only replace Lucas with Todd, and Jones with Vault Boy.
Couple that with Emil giving a helping hand.
