So there is this film the gorge https://feddit.uk/post/21188415 and there was this anime where they had a team that goes down a hole in the artic or something and fights demon things and it feels to me that is what this movie is about unless Im misunderstanding the previews.
definately not hellshing, rifureta, and Solo Leveling as I quite remember those. I googled the rest and nothing is resonating. I only watch stuff that was free on funimation and now crunchy roll and im almost sure it was one were like the first 4 episodes or something was free. I feel like it was a think where one or two mains were put in with an experienced thing type of trope and the old guard where like stay out of the way and I feel like they had some special talent or ability which made them part of the team and they stopped something that really impressed everyone. Where they were going was I swear like down into a pit in the earth or something. Ugh. sorry I don’t remember much but the movie trailers just tickled something in my head.
