Killing off Snoke and Phasma after only two movies I thought was a big twist.
I wouldn’t be at all surprised that Phasma is still alive. There was foreshadowing of a laser blast which simply deflected off her armour just before she fell through the flames, so I think the film makers could in good faith have her return. Snoke less so!
wasted talent of Snoke and Phasma could have done them better
