I was just thinking about "Finishers" in the game. Something usually associated with action games, stylistic finishers add a bit of "Badassery" flair to kills, but, playing many games, I have some issues about them.
I personally want them to be optional, basically for all the reasons I listed in the poll, but most of all, because they interrupt gameplay, being scripted and random, thus out of the player's hands. I only hope, at the very least, they don't happen mid-battle and allow you to get killed by something else attacking you from behind.
