It is quite weird when you want to watch a super hero movie, with action and some fun, and you get a drama. You still have the superheroes, but old and decrepit. And when you lost your mother a couple days ago, it gets even sad. Specially as (spoilers…) both old and decrepit heroes end dead.
While the drama is the main flow of the movie, you have a couple of fun moments and a couple of action. But in my opinion it lacks diversity. After a couple moves it gets repetitive. I think that the director could take a little more of the new mutants diversity (you will understand when you see the movie) for a funnier battle.
