AKA: Old Alien and the Mountain
End of season cliffhangers are a risky business, not least because they require a degree of certainty that the series is coming back. You want to give the audience a desire to return without making them feel like they're being manipulated. It's a fine line to walk, but if you do it right, you can keep your audience always coming back. There's a reason why I'm writing this review while watching Orange is the New Black. Fumble it thought and the audience can feel they're being manipulated for cheap effect.
