*Spoilers ahead*
So I bit the bullet and watched this movie. I guess it's safe to say it did not end well.
A movie with a cast like Bill Murray, Chloë Sevigny, Tilda Swinton, Steve Buscemi and they still couldn't pull it off.
The worst part is that out of everyone, only Chloë seems somewhat freaked out about the Zombie Apocalypse. It seems mildly inconvenient for some of them where as others have no survival instinct whatsoever. The worst part is the thing with Aliens which doesn't fit into the story and makes no sense at all.
All in all, this is a slow dull movie with disinterested characters which is a bad look for a zombie movie. Do yourself a favor and skip it.
