The New Mutants by Marvel Comics'
It's based on the New Mutants comics.
Synopsis:
After a near-death experience during a strange tornado, Danielle Moonstar awakens in an abandoned research facility run by the mysterious Dr Cecilia Reyes. There, Dr Reues introduces Dani to four other equally uncommon teenagers: Illuana Rasputin, Rahne Sinclair, Sam Guthrie, and Roberto da Costa, who wants to keep them safe and sound until they learn how to be in full control of their extraordinary abilities. However, even though the exceptional team of traumatised inmates believes that they're being treated and cared for, before long, they all start to experience horrifying hallucinations. But, this institution was supposed to be a safe place. Are they patients or prisoners?
Recommendation:
A film for superheroes and horror movie lovers. It is a mix of horror, action, suspense and science-fiction all in one. The main characters are mutants like the X-men generation but their powers can be destructive and terrifying, that's why they are isolated, but it might be for that long because when they start to not feel protected they will fight as a team to survive and get out of their prison.
