Oh wow, S3 felt like an ending, this definitely comes as a surpriseI think it's just that they wrote the S3 finale knowing that it might have to serve as the series finale but they didn't know for sure. They even called the episode "Future Unknown".
And I'd hope it gets at least a sequel and even becomes like a full on franchise.Same.
Yeah, plenty of shows do this.It feels like a minor miracle that we're getting season 4 so I don't want to get my hopes up too much. But it would be great if we do get at least one more season after this and there's definitely potential for spinoff shows in that universe.
I, for one, hope that it gets more seasons. 5 at least would be nice. And I'd hope it gets at least a sequel and even becomes like a full on franchise.
