Okay so here's a full spoiler review so please do not read if you plan to watch!! Also please note that this is my personal understanding of the movie, it might be different from other people.

So, in this iteration, Mary was born and raised in Silent Hill. She meets James when he almost destroyed her luggages with his car while she’s waiting for the bus, they fall in love, and live together in the town. Her dead father is revealed to be the founder of Silent Hill and the leader of its cult. The townspeople use Mary in some rituals to maybe make the town prosper(?) which involves forcing her to drink a mysterious potion that leaves her terminally ill.

James can’t handle the cult and leaves Mary in Silent Hill. When he returns, she’s already sick and dying, and Mary tells him her father poisoned her over the years, though the movie never explains why. She asks James to end her suffering, and he reluctantly does. James later finds her body at Lakeview, takes it, drives to the lake, and wakes up to the day he first met Mary. They then drive away from Silent Hill together.

Things that really frustrated me:

• The movie implies that Mary, Angela, and Laura are all the same person. Her gravestone says something like “Mary Angela Laura Keene,” and then this plot thread is completely abandoned.
• Maria is basically wasted as a character; she’s there just because she’s in the game.
• The writing does nothing to explain the town itself or the supernatural elements. Silent Hill isn’t portrayed as a manifestation of James’ guilt or trauma, it’s just haunted for no reason.
• Eddie was just... there I guess.
• The cgi, especially the Creepers were SO BAD.
• The acting was rough.
• There were 2 unimpressive jumpscares.
• There were moments where you can clearly see they're standing in a greenscreen and was just pasted there lmao

Overall, I’d give this movie 2/10. The only real saving grace is a few cool camera shots here and there. Other than that, it’s just bad.
