After hearing about who Finn was before watching the movie, I was pumping myself up for Stormtrooper Spartacus starting a mutiny on top of a Super Star Destroyer. So yeah, I was pretty disappointed when I actually saw the film.

I thought it was kind of twisting the knife how, in the third movie, they actually gave Stormtroopers a moderate range of male and female voices as if to humanize them (as opposed to the "Generic North American White Guy" voice in the OT), but didn't do much with them aside from showing them getting blasted and stabbed. The whole half-baked introduction of other renegade stormtroopers was just adding insult to injury on "what could have been".
