I voted "gah!". I do remember cinematics being annoying in crucial moments (and pressing pauses stops the cinematic also, which is logical), and it probably costed me a few soldiers from time to time. But they're nice.
Of course I'm all for a setting which would able/disable them. As I don't mind not having it, but I don't mind having it.

To sum it up: Vuk, go for the toggle button!
