I've spent weeks working through 3 seasons of Colony and I just finished the finale which ended on a huge cliffhanger so I check when season 4 starts and nope, cancelled. This shit happens far too often, I wish Netflix, Amazon etc would come up with an icon or anything to let you know the show ended on its own terms or at least had the chance to wrap up properly. Unless I'm blind Netflix doesn't even tell you if the show has been cancelled. It's like buying a book with the last 30 pages missing.
