Done in quotes because sometimes shows get cancelled or otherwise abandoned and other times it has a final season or only had one season and was properly finished. Either way, same result.

I don't have the patience or time to keep track of what series is having what new season come out at what point. I prefer to just wait for it all to be done and then watch in my own time. Even if it is one of the very few series I watch that isn't "done" I still don't do the weekly episode thing. I just wait for it all to come out and then watch as I please.

That said, I have a backlog of series that are on my to-watch list, either suggested by friends or I saw a trailer that looked good, but they sit there at present because there's so much utter shit SEO spam websites that you can't get a clear answer if a new season is coming or a series is done or not.
