I feel like Lee's suggestion is not really what I would go for.
A side view to express anger and emotion does not necessarily work better, as you will show much less of the face, and it is also less immersive.
I think the addition of a second character (receiving the emotion) is great though. Wherever it is in side view or front view.
Whichever view I'd chose, I would personally try to make the scene/character feel a bit more dimensional; and use the lines that show in that view to exaggerate the emotion (e.g. in side view, you can really play with the line of action/spine of the character; in front view, you can really play with converging lines towards the receiving character).
