‘Hindsight is always 20-20’ which means it’s easy to say how something would have been successful after the fact.
I mention it because prognosticators at The Hollywood Reporter have decided that Marvel Studios had dodged a bullet by abandoning plans for a feature film based on the Inhumans.
And that’s entirely possible, though the reasons why the writer came to that conclusion are weak as best because whether or or not comic is successful or not is almost irrelevant (to general audiences).
Using that logic there would have not only have been no Blade, Blade II or Blade: Trinity (I include the latter because it was the last Blade movie, not because it was any good–it really, really wasn’t) because Blade, first appearing in Tomb Of Dracula in 1973, was at best a supporting character.
Despite this, he’s appeared in two hit movies.
The same thing can be said for Ghost Rider, who was also featured in two movies.
What both Blade and Ghost Rider prove is that you don’t need a ‘successful’–which I interpret more as prolific or being a huge, best-selling title–existence in comics to make a successful movie based on the character.
And let’s not forget Black Panther, likely the most successful superhero introduction ever.
This is despite that in the comics that spawned him, he never seemed to quite get his due. He first appeared in the Fantastic Four in 1966 and has popped up many times since then, though typically as a supporting character.
Yet he appeared in Captain America: Civil War in 2016–his first appearance in live action–and not only did comics fans lose their collective minds, but the appearance laid the groundwork for his solo movie, which went on to earn over $700 million at the domestic box office (though perhaps of greater significance is that it earned over $646 million at the foreign box office, where films led by African-American actors–never mind a movie with a cast almost entirely comprised of them–typically underperform).
I think have shown that whether or not a character hails from a successful comic has little to do with whether or not a character is successful in live action, so if Marvel Studios were to base a movie based on the Inhumans–and if they were to take the same care with it as they did with their other projects–there’s little reason to assume that it wouldn’t be successful as well, which in turn would have likely resulted in a successful comic line.
