TL;DR – A perfectly okay film but a bit of a missed opportunity.
Post-Credit Scene – There is no post-credit scene

Review –
After thirteen films, and running for twenty years, the current X-Men franchise has drawn to a close. Today we review the last movie in the series The New Mutants, though it was never planned or designed to be a swan song it is what it has become. Well, let’s dive into a film that swerves into the horror of what it would be like to wake up one day with powers.
So to set the scene, we open in on a reservation in America when Danielle “Dani” Moonstar (Blu Hunt) is woken up by her father William (Adam Beach) and told to run. All around them, some outside force is destroying the reservation with snow and flames everywhere. William asks Dani to hide in a tree and goes back to help only to be killed, Dani runs form the oncoming storm and crashes down the side of the hill, hitting her head. When she wakes up, she is handcuffed to a medical gurney in what looks like an old hospital. Over the speaker Dr Cecilia Reyes (Alice Braga) askes her to calm down and lets her know she is safe, but that she was the only survivor of her reservation, everyone she knows is dead.
