Yes but every character that is born/given/burdened etc with a great power will find it difficult to deal with. It's a part of the characters journey and struggle to accept it. It makes the characters more relatable to the audience if they struggle and then overcome that and rise to greatness. It might be a Hollywood cliche but we eat it up because who doesn't love seeing someone overcome adversary? Yes they are fantastic but getting that kind of power would be intimidating. They'll accept their powers and use them to do good that's the whole point and journey of the character. Fox obviously feels like showing this again with these characters. Not every character just goes wow I have a power. Not everyone wants to be great. Most people in the world just want to be normal. Whatever normal is.
This may all be true, but when someone is telling a story they choose what to show and what not to show.
In Jaws, city boys Brody and Hooper had to deal with going to the bathroom in either a tiny squalid on-board facility or more likely over the edge of the boat. That's a reality that anyone spending several days on a small, run-down fishing boat would have to deal with and it likely made an emotional impact on Brody and Hooper . . . yet we didn't see that in the film.
There was a clear intent of The Fantastic Four comic books and that clear intent was to tell fun, out-of-this world fantasy-adventure stories. The intent was never to tell the harsh reality of radiation sickness, cancer and death that would result from large amounts of radiation.
As I mentioned, superhero films are obsessed with the 'problems' associated with being superheroes to the point it has become cliche'. This isn't a fresh and original take. It's the same thing we've been getting from most comic book films for the past 15 years.
If I were making this film and someone asked me: "What's this story about? What will make it unique?"
The answer to both those questions would be the same single word answer: "Doom"
The primary conflict of every comic book I've ever read has been the villain and Doom is one of the best we've ever seen.
We haven't seen a truly great comic book villain yet (I had hoped Ultron would be that villain, but we saw how that worked out), so previous efforts have left the door wide open for a comic book film like we've never seen before.
Let's not spend time futzing around with the characters and their minor problems. Let's focus on the real conflict - the threat posed by a villain that's scary as s*** if done right and the threat he poses to the world if our heroes can't defy the odds and stop him.
Unfortunately it looks like we're going to get something that is very much like films we've seen before.
