Although the studios have recently started to backtrack on the idea of announcing and handing release dates to sequels before the first movie has even been released, it seems hard to believe that the approach has changed behind the scenes.
After all, if they're investing so much money into a product specifically designed to appeal to the widest possible audience and make the greatest amount of money, there has to be some sort of plan in mind for further adventures even if they won't comment on it publicly.
On the downside, there's been a huge number of blockbusters that are always labeled as being the first in a trilogy, which isn't a great PR move because it basically tells audiences that the movie they're paying to see won't tell a complete story.
It seems incredible to think that people thought we'd want six King Arthur movies, seven Power Rangers or an entire Dark Universe before we even had a chance to discover that the opening salvo sucked, but there's also been a lot of franchises that kicked off with some phenomenal movies before eventually succumbing to the law of diminishing returns, with both their quality and reputation taking a nosedive in the process.
I don't do social media, so like or follow me in person but please maintain a safe distance or the authorities will be notified. Don't snap me though, I'll probably break. I was once labelled a misogynist on this very site in a twenty paragraph-long rant for daring to speak ill of the Twilight franchise. I stand by what I said, it's crap.
