My rough cut of the first 3 episodes is still only 53 mins with some brief flashbacks to be added, which shows just how little of these episodes progresses the story. Total time of the flashbacks is 71 mins, so there is still a chance there will be enough material to warrant a separate movie.

Well, episode 4 brings another 30 minute flashback. The material does seem to bring an end to the flashback story and I think it would work well as a conclusion to a standalone film.
