Until I saw it. This damn film has been to Limbo more times than Illyana has. It was not worth the wait, it seems to suffer from some sort of technovirus in addition to many questionable story and plot choices.
Here is the run down of the character's names and powers:
Rahne Sinclair, aka Wolfsbane. A mutant that can take the form of a wolf or a transitional human/wolf form. She has all of the sense of wolves plus more strength and perhaps a healing factor.
Sam Guthrie, Cannonball. Can generate thrust anywhere on his body to propel himself through the air. While thrusting, he is impervious to anything. He does not have a healing factor.
Roberto "Bobby" da Costa, Sunspot. Bobby has the ability to absorb sunlight and use it to empower himself with great strength, invulnerability and flames.
Danielle "Dani" Moonstar, Mirage. Dami has the ability to project people's greatest fears and make them real. Historically, she not good at nicknames. Not only has her character changed her own code name in the comics several times, she doesn't even use other people's code names. A rare inversion of the "movie stars have no comic book codenames" trope.
And finally, Illyana Rasputin. Magik. Oh, boy. She's a sorceress with a magic sword, the ability to teleport, partial body armor, a tail, and a baby dragon.
There are only three other characters, Dani's dad, the Demon Bear and the evil doctor Dr. Cecilia Reyes who can make force shields.
The film does a variable job at depicting the character's powers on a budget. The effects were on-par with Ready Player One which is not a complement. Ready Player One was a massive mashup of decades worth of video game art which works in that film. It isn't great for other film types like New Mutants.
The whole premise of the movie didn't make sense. The kiddos are trapped or staying a hospital for mutants. The hospital had a staff of one, Dr. Reyes.
Now, I've had a bit of experience working with kids and young adults. The first rule of these sorts of operations are two deep leadership. If you are not using two deep leadership, you're an imbecile. Dr. Reyes is an imbecile, she's trying keep the kiddos in the hospital all alone. Sam, Bobby and Rahne have given themselves over to the idea of staying. That kind of works. Dani is uncertain as to what is happening, leaving her open to staying or escaping as the chance presents. That doesn't go well at all.
The final character, Illyana has something else going on. She's a mass murderer and can teleport. Why is she still here, if not to kill everyone else in the film? And she definitely hates everyone, in a nasty condescending, racist way.
As far depicting superpowers, they did a good job for a few of the characters. Sam's blasting ability was a great special effect. Dani and Rahne power's appear reasonable well done, magic and werewolves are classic B-movie fodder. They couldn't have done this poorly if they had tried. I think they tried. Bobby's abilities were just ho-hum. Illyana's powers come off as a cheap video game most of the time for no good reason.
Magik has the most wide ranging abilities, each with a vast scope. But they attempted to confine her character in tight spaces, like either Nightcrawler in the Oval Office or Captain America in the elevator. It was not a good choice because she has a massive frickin' sword. It looks like she can't fit in those spaces. When she gets out the open, they do a far better job at displaying her powers but by that time they had already decided on the video game style which wasn't applicable to the filming process.
Far too much time was spent on Rahne, who is a the most likeable character in the film but not the protagonist. They were one step away from having "The Wolfsbane Movie" and failed to make it. That would have been better than this, even if it was called, "A Werewolf in Starbucks".
My favorite bit was everytime Sam used his powers. He displays these brilliant blue/orange shimmery flames like charcoal on the grill which is an amazing play on his character. Magik was shown trying to knock the Demon Bear into Limbo. It made perfect sense since she couldn't win in straight combat, but this tactic was negated by the strange video game special effects. It was kind of hard to tell that was her intent rather than random flashy scenery. The Demon Bear was awesome and terrifying, but the viewer shouldn't be rooting for the villain.
All and all, I give it one and half stars of five. Maybe you should read my 5 star review of Dungeons and Dragons (2000) to evaluate how not good this was.
Now showing on HBOMax, but you could wait a bit longer.
