A surprisingly touching horror film loaded with gripping suspense and intense action scenes

Rating: 8/10 (31 August 2018)

Some of my favourites are 28 Days Later, Zombieland, and A Girl with all the gifts: I prefer memorable characters, action scenes, dialogues, introspection about humanity, suspense, and dark humour over gory jump scares.
This movie, albeit predictable plot lines and character stereotypes, the actors and pace engage the viewer to root for their (good & ill) fates. Characters' actions mostly remained convincing: their behaviour is driven by consistent, reasonable motive, and some characters transformed through meaningful incidents naturally, not in a sudden to fit the ending. Each survivor is well acted.
Camera work was effective in portraying a sense of dread and chaos, while keeping focus on the main characters and plots moving along the train corridors. At 2 hours in length, there wasn't much dragging scenes at all. I just skipped the character intro (10 minutes), and from then on, the story runs along.
How realistic is the ending depends on the viewer: are you an optomist or a pessimist? Either way, it's 2 hours well spent.
The 15 minute behind the scenes bonus feature actors and production crew rehearsing, teasing each other, including bloopers, quite a strange shift in mood :)
