MCU: 10 Reasons Hulk Deserves Another Solo Film
7. The Hulk Is One Of The Most Unique Marvel Characters
If you look at the majority of MCU characters and their abilities, Hulk is a very unique character in the fact that his power is a curse. This aspect of The Hulk's character isn't as applicable since his transformation into Professor Hulk, but if the film-makers chose to do a prequel over a sequel they could delve deep into the true horror of Banner's curse.
One of Banner's best scenes in Avengers is when he explains how he actually once tried to kill himself but the 'bigger guy' spat the bullet out. This dark confession was mostly glossed over but it goes to show Banner's story is inherently a lot darker than most of his co-Avengers. Disney may be sceptical about delving into some riskier stories but the pay-off could be great, and it's about time we saw some R-rated MCU films.
Furthermore just because he's now Professor Hulk doesn't mean that his life is a bed of roses. We don't know for sure that Banner's solution in a permanent one either, and the curse of being The Hulk may make a return.
