X2: X-Men United (2003)
“Have you tried… not being a mutant?” X-Men 2 really did do quite a lot of interesting things, and not just as a precursor to what would eventually become the superhero movie boom. Bryan Singer’s darker take on the comics really did emphasize the aspect of young people dealing with prejudice as they learn more about themselves and their bodies, though in the end it remained focused on the Wolverine’s past storylines from the Return to Weapon X comic storylines.
