You can exit VATS immediately by right-clicking.

Melee finishers in VATS are quite amazing though, atleast swords and knifes (knives?).

Thank you, I will try that!

There should be a toggle for kill cams because in a roleplaying game characters can be wildly different. If we roleplay an epic fighter, a kill-cam might be completely appropriate. But if we roleplay an "ordinary" person - a farmer or merchant relatively unskilled in combat, for instance - then grandiose cinematic kill-cams can feel completely out of character.

My opinion is that anytime a game imposes a feature like this on every character, it violates the spirit of roleplaying.

No, I use a mod to disable kill cam in Skyrim.

No kidding. That video triggered my nostalgia of that game.
