Every time the game switches from gameplay mode to movie mode, your attachment to the player character switches from 100% emotionally invested, to 100% detached. That’s pure, jarring, dissonance right there.

You could say that they fill out the visual experience quite well. However, every once in a while, an intertitle comes up.
