It is the season for all things spooky and scary. In the spirit, I would like to recommend the South Korean zombie film Train To Busan.
The film is a fun, zombie film set on a bullet train and has plenty of fantastic set pieces and a lot of heart. Not only that, but I believe it has a complete storyform. The 93% on rottentomatoes seems to back that up.
It is available to stream on Netflix in the US. On an episode of Writer's Room @jhull mentioned the lack of horror stories on Subtext and I think this would be a fun analysis.
If there isn't an interest in doing a group analysis, then just take this a recommendation for some enjoyable Halloween viewing.
