The events in the movie about an 1 hour and 12 minutes is roughly 2-3 episodes of "missing" information and story line that are crucial elements to the new season. In order to truly appreciate what is going on in K: Return of Kings, as it is only in it's 4th of 13 episodes you need to watch the first episode, the movie, then the second episode in order to follow what's going on in episodes 3 and 4.
It will clear up the murkiness between the movie and the new season. If you watch it in that order. Honestly it's worth the extra effort and re-watch. I'm totally loving this anime. It's exciting, action packed, awesome fight scenes and cinematics. I'm reviewing both the movie and new season as a package deal. Because you'll totally be lost in the new season if you don't watch the movie. Thanks for reading! Enjoy the show! ^_^
