Netflix needs a "This item will be removed in X days" so I can binge watch shows in the right order.

I'm using the UK Netflix on a SmartTV; I want to know how long Dexter is going to stick around so I can decide if it's worth me starting or not.

I can Google it but I want something actually on Netflix to give me a timeline. Not suddenly tell me "Oh yeah, you've got a week to watch 6+ seasons of whatever".
