Breaking Bad set the bar very high for great endings...
And I thought Game of Thrones set the bar very high for the quality of visual entertainment that you should expect on your 4k home theater, even if the story suffered from time to time.
GoT was total eye-candy, a big screen cinema experience in your living room and they absolutely established the bar with this.
In fact, I think shows like BB and GoT are hurting the motion picture industry because now audiences have grown to expect the kind of deep, detailed storytelling that only a multi-season series like BB can deliver as well as the world-building, the sets, costumes, and FX that shows like GoT delivered.
A 2-hour movie these days just feels so unfulfilling.
The trade-off however is that with shows like these, there are a lot of people who are going to sit them out until there's a few seasons and then binge everything in a few weeks.
I didn't watch a minute of Breaking Bad while it aired, not starting it until about a year after the series concluded. I didn't watch GoT until Season 6 was airing and then I binged the previous seasons.
A lot of people want to be ensured that the network is going to commit to the show before they commit their time to a series that winds up getting cancelled before it concludes (I'm talking to you HBO and "Raised by Wolves").
