Then move your mouse or thumbstick....left
Well, I think the main difference was I played Oblivion on the PC and Fallout on the consoles. Therefore with the PC I don't have a problem hitting my targets, but with the console games, it would help a little.
But seriously, why does this have to be a bad thing? It could just be for the finishing moves for each weapon. Like when you finish off someone with a shortsword, maybe you automatically catch someone's neck. And to keep this from looking sloppy, such as right when an enemy moves, they do the magnetism thing. (Also, its better to edit your post rather than double post... Eh, who cares. The mods don't usually complain.)
