I'm sorry, but most of the vamps mentioned here have been injured by others whilst moving at normal speeds. That's also ignoring the speed feats that Force users are capable of which is quite handy. They all have some level of precognition, especially if they are fully opened to the Force. Sidious could surround himself with lightning as soon as he feels his attacker moving toward him. All of them are capable of shielding themselves from impact in the Force. Their speed with sabers is ridiculous, and with the exception of Maul having to try to block Blade's machine gun, there's nothing about the vamp's speed that is beyond what they have been shown capable of in the books or films. Actually, there are even scenes with saber duelists blocking a spray from fletchette weapons.Maybe someone could explain what I'm missing. Dracula in mist form, Vader crushes him into nothing with the Force. Black Hat was destroyed nicely by a train explosion/crash, which I'm sure Dooku could mimic the impact of with an explosion of Force power within his body, or even just his heart and brain. All of the Force users are capable of crushing any of their skulls and walking away without breaking a sweat. The vamps have zero defense against the Force and the Force users can match the speed feats. If you don't recall it's capabilities there are examples at the beginning of the Phantom Menace and in some of the CW toons.
Anyway, there's nothing to stop any of them from pinning the vamps in place with the Force and decapping them at their leisure. Luke pinned Caedus to a chair and the Sith was a more than capable Force user, so what is someone who has no Force ability going to do? This is why pitting people from universes with utterly different rules doesn't work very well.
1st off the OP clearly states that only movie versons are to be used so no matter how much uber shit these guys have done in the books/comics they are limited to their movie portrayals only. And from their movie showing their speed is not matching most of these vamps.
When have any of these Sith crossed a room as such speeds that no one can react like Russel has been shown to do easily? Even when surrounded by other extremely fast vampires Russel just appears to be a blur to them. Or when has any of these Sith covered miles in moments like that homo Cullen? They are just outmatched in the speed department.
Force users have pretty fast reflexes as well, and I doubt every vamp is gonna try a speed-blitz right from the start.
Faster than human no doubt but not anywhere near as fast as these vamps have shown. Black Hat looked like he punched a guy. Just punched and the guy went flying super far. Then after a moment the guy realised he wasn't just punched but his heart was actually ripped out. Do you realise how amazingly fast you'd have to be to pull that crap off. The Priest didn't even know his HEART had been forcfully RIPPED FROM HIS CHEST!!!!
Now if the Sith were allowed their book showings then you'd have an argument but in the movies they were nowhere near the speed they need to be here nor do they have the power showings (lightning shields, holding people in place, moving faster than eyes can follow, ect)
