Another aspect is the marketing strategy. Marvel has always been great at promoting their movies. They release trailers at the right time, do a lot of tie - ins with merchandise, and build up anticipation long before the movie is released. Also, they target a wide range of audiences, not just superhero fans. Their movies often have elements that can attract families, action lovers, and those who enjoy complex storylines.
One thing is the power of building a shared universe. Marvel has been really good at connecting different characters' stories. Like in 'The Avengers', they brought together heroes from different solo movies, which created a huge hype and more depth to the overall story. It made fans excited to see how their favorite characters interacted with each other.
We can learn the importance of strong character development. For example, Iron Man was initially a self - centered billionaire, but through his journey, he became a selfless hero. This kind of character arc is very appealing to the audience.
