how bout a beginning cutscene, which introduces the game, a middle cutscene, the big plot twist, and an end cutscene, which is the end.
That could work, depending on what the cutscene was, in the middle plot twist. I remember how Bastila was kidnapped in KOTOR1 and you had no control over it? I kind of like how Deus Ex handled things which I don't remember having too many cut scenes. When you were captured by the German, it was an impossible fight against him but you had the option to keep on fighting him until you were captured. You found out your brother or that friend of yours in UNATCO were still alive not through a cut scene either. I prefer game developers writing the storyline to directly involve the player rather than taking control away through a cut scene. Providing more choices during the storyline makes for a better game.
