I'm having a hard time figuring out why anybody would like finishing moves. I don't mean any offense to anyone - I just really can't figure it out. I mean - obviously people do like them, or at least that's what the poll results say, but I can't imagine who would or why. I would tend to think that the roleplayers won't be much impressed by them, and might actively oppose them, just because they're not that focused on combat. I would think that, to them, they'd just be sort of unnecessary and cheesy. At the same time though, I would tend to think that the action/adventurers won't be much impressed by them either, and might actively oppose them too, because they take control out of the player's hands. The idea of the game, from an AA perspective, is to win at combat because of your greater skill - not just to push a button and watch a cutscene. So I'm just having a hard time figuring out who it is that they do appeal to.
For the record - I hold pretty much all of those opinions. I think they're cheesy and unnecessary AND I don't like losing control of my character. Any time a game has any cinematic feature like that, one of the first things I do is turn it off. I just hope I have that option in Skyrim.
From what I understand, finishers will be animations, not cinematics or cutscenes. The animation that you get will depend on which weapon you are using and which enemy you are fighting.
I don't think it's fair to say that finishers take control out of a players hands, because finishers are initiated by a power attack, a power attack that was made by the player. The only time that the player won't have control is during the animation, which will be brief.
When I think of finishers, I think of satisfying endings to hard-fought battles. It will be nice to plant my axe in a Draugr's skull after fighting tooth and nail with him.
