I find that (passive) cutscenes have nothing to with the interactivity of a videogame.

If gameplay is at least not bad, if it is average, or servicable, but the cutscenes are outstanding, it could be an outstanding game to me. If gameplay is bad on the other hand, there can hardly be redemption. (Could be possible, but hardly.)

But OP seems open for discussion, if a cutscene is even part of a game. And there sure is an argument to made that it is not. It literaly cuts the game to present a scene. If it is not played, it is not a game.
But this is not true in my opinion. To me, a game is the whole package. A cutscene in a game is sure part of the game. You are not buying a game and a movie, but just a game. It does not have to be interactove 100 % of the time to be 100 % game.
