Series like this should be called out for what they are: A scam

So there you are: hooked on a story, investing time, watching the commercials and then BOOM! Cancelled.
No ending, no conclusion, no satisfaction at all.
Just some company that just got a little richer from the sponsors.

I mean, I get that when production is expensive you don't want to continue when your views are low, but at least have the decency to give the people that gave you their loyalty some sort of closure. They invested in your product, made it valuable and profitable and you give them nothing?
How do we call that? Promising people something, letting them invest and then leaving them with nothing... Ah right:
A SCAM.
