On a scale of 1-10, I'd give it a 7. It's a mid-tier X-Men film for me. Plot is pretty straightforward, but the cast chemistry kept it very engaging and I liked the slow build to the use of mutant powers. The hospital sort of reminded me of Clockworks in Legion. Of the main cast, Blu Hunt, Maisie Williams, and Anya Taylor-Joy were my favorites.
The brief acknowledgements to the greater X-Men world had me grinning because I figured this wouldn't have any nods whatsoever, including that one surprising reference. So I enjoyed it. Nice to see, again, something done different with a comic book film, even though this felt more creepy than outright horror, as the first teaser hinted. Glad I saw it and it was nice to be back in a movie theater, but in the end, I guess slugzilla was right.
The New Mutants never came out in theaters after all.
