The dramatic incidents of this movie depict the king Regis from the Lucis land, which full of sacred crystal and most of empires try to steal these crystals that gives the land magic and power but the king Regis with his soldiers stop them and protect Lucis from any danger.
Kingsglaive's sole purpose is teasing Final Fantasy XV and if you have no interest in spending hundreds of hours of your life playing it, then don't even bother.
Kingsglaive won't set the world on fire, but it might just be the best movie that bears the Final Fantasy name. That's not a high bar, but it's an accomplishment.
If the look of the movie should please fans, the plot is an absolute muddle-an unholy brew of flotsam and jetsam that ranges from Wagnerian motifs and garbled Latin names...to bits of 'Star Wars' and 'The Lord of the Rings.'
Kingsglaive is an incredibly beautiful film with a lot of fun nods to its Final Fantasy origins. Unfortunately, it never quite finds its footing story-wise, even with the help of some incredibly talented actors who breath life into their roles.
Instead of trying to adapt the video game experience into a film format, Kingsglaive transforms the movie-going experience into something familiar to video game fans. It's essentially a really long cutscene.
