I only watched the first seasons but I feel like this is a bad move from a Netflix business perspective... next one was slated to be it's final season anyway and would have wrapped up the show. By the sounds of it, it ended unfinished instead.

Cancelling shows without a conclusion is not a path Netflix wants to go down too easily; people are far more reluctant to get into a new show if they don't feel confident that it'll have a conclusion of some sort. If people start feeling like Netflix will cancel without consideration for the audience then their viewership of scripted drama will drop. It's that simple really. I personally am of the belief that shows should ALWAYS get a conclusion; and that "early cancellations" should always get a slot for maybe a 2h special or 4-episode mini season or whatever to find some way to round things off.

e.g. I have MASSIVE respect for The CW for bringing One Tree Hill back after ending for a "surprise bonus" half season to properly conclude. Also the "fan power" that allowed the "Serenity" movie to happen to conclude Firefly. Just makes a huge difference.
