The Game of Thrones controversy proves how futile episodic series with strict continuity are
Bond is the most successful movie franchise of all time fundamentally for one reason: you have an established character and formula that can be molded into something new every few years. Until this current crappy Daniel Craig era, you could watch any Bond movie in any order. When I was first allowed to watch Bond movies, my dad would take me to the video store and then I would just randomly choose which Bond movie I wanted to watch based on the dvd cover. I saw For Your Eyes Only before any of the Connery films, so I didn't even know that the guy in the wheelchair in the opening scene was Blofeld on my first watch. That's seemingly an important detail, and yet it didn't matter at all. For Your Eyes Only is a complete film with a beginning, middle, and end that doesn't require you to have ever watched any other Bond movie to understand. This is something rare and special in any entertainment medium.
The Bond formula is a safeguard against all of the problems that most other series face. It used to be that if EON made a crappy Bond movie, then all the fans would have to do is wait another two years or so for the next one which would be a fresh start. The events of the previous film wouldn't have any bearing on the new release. This constantly kept the series fresh and it allowed for seamless changes in the casting of Bond and other supporting characters. Other series have a very hard time getting away with major casting changes unless it is a reboot or remake many years after the previous version.
So look at all these other series that have the inevitable crappy ending. I've never watched GOT, but now I see that after so many years of this show being popular to a level that has never been seen in television, fans are petitioning for the latest season to be remade. All those years of dedication have been flushed right down the toilet because the current season has retroactively made every previous season and episode worse. The same thing happened with the Bond series in SPECTRE. Casino Royale and (the inexplicably exclaimed) Skyfall may have been wildly popular, but now they are retroactively much worse than they were on release day because of the events of SPECTRE. None of these films can be enjoyed in isolation anymore. There are so many other examples of this. Look at the Harry Potter books. A lot of fans didn't like book #7 but tolerated it, and now the Cured Child play is apparently so bad that most fans consider it to be glorified fan fiction. What about Star Wars? The new trilogy has been poorly received, and that's a problem because it is a direct sequel to the beloved original trilogy and has harmed the appeal of even main characters like Luke Skywalker. I have even heard that a lot of fans are unhappy with the new Avengers: Endgame movie. So all those dozens of hours of investment into the MCU have been retroactively ruined by the latest entry. I remember reading an article that said you would have to watch something like 40 hours of MCU movies to catch up to the events of Endgame. Imagine wasting your time on all that just to get a crappy conclusion.
When has this trend ever been avoided in an episodic series? Lord of the Rings is the only book/movie I can think of where most fans are are satisfied with the ending. What else? This is exactly the trap that every series falls into.
Think about this for a second. I know it's been about five years, so you've probably forgotten (and most people probably forgot about SPECTRE a few hours after watching it), but James Bond and Ernst Stravo Blofeld are brothers. Take a few moments to actually reflect on that and think of what the implications are because this is a detail that seems to have been completely overlooked. James Bond and the main villain in the whole series, the crazy guy who runs a criminal organization known as SPECTRE and is constantly plotting to take over the world, Ernst Stravo Blofeld are brothers. How is this ever going to be salvaged? EON can either spend the next ten or more films trying to somehow salvage this mistake, or they could just scrap it, pretend it didn't happen, never acknowledge the events of SPECTRE, and move back to the tried and tested Bond formula. That's what they should do, but I wouldn't count on it.
