I watched the film Exit Humanity this week, it took me several sessions to finish it. I didn't feel compelled to watch it all in one or two sessions, I think it took me four sessions. The film does organise itself into several chapters, the chapters of the main characters journal as he goes through a zombie nightmare at around the time of the American Civil War.
I felt the story was too long and not enough was happening in it. I didn't really like any of the characters in the story. The zombies were slow moving (like the film) and the bad guy wasn't developed well enough to really care if he was defeated or not.
There was a lot of groaning and wailing and shouting but not a lot of action.
