Eventually it will be all bad, Disney intend to release a new Star Wars movie every year for the foreseeable future, when this trilogy ends there will be another which is already planned, then there will be another and another until the majority of people will be sick and tired of Star Wars and it's no longer as profitable or they move onto something else that makes them even more money that they can ruin. Disney only care about 2 things and that is power and money which often go hand in hand. There's a really "nice" Grand Masonic lodge underneath Disneyland in Florida, I can't say any more because this isn't in the right section.
There's loads of amazing franchises that have been killed by saturation, I loved the first
Police Academy movie and even the 2nd was pretty good, but the 3rd was just okay and the same old jokes were starting to become tiresome, but they were still going with Police Academy 6 when most people were sick of it, then there was even a Police Academy 7 which was called Mission to Moscow, but this still wasn't enough, they even also had to release a spin off TV series that most people have probably never watched because by then the franchise was virtually dead and it completely flopped. I watched 1 episode of the series and it was dreadful, they'd obviously completely run out of ideas because they were resorting to a story line that featured a pathetic incarnation of Count Dracula who was going around hypnotising police officers with his gaze, yes it's so bad it's actually quite funny, but the series itself wasn't and it was an insult to the original movie. Now it's been a good while there's been talk of bringing it back yet again with a reboot which I suppose might work for a new generation, but my point is saturation killed what was an excellent franchise. The reason why Star Wars remained so special for so long with so many fans was because they kept it to just 3 movies for such a long time, even the 2nd trilogy made Star Wars less special and unlike the original trilogy that were stunning they had mixed reviews. Yes some franchises can last for longer, but even franchises like James Bond have in my opinion been killed, especially after they'd run out of Ian Fleming books to base them upon. Look at classic James Bond movies like
Diamonds are Forever (1971) and
Live and Let Die (1973), then compare them to the very latest movies, I definitely know which ones I'd prefer.
