Just all around a dreadful occurrence in film history.
The main protagonist checks all the boxes on the "dumb things to do in an apocalypse" checklist. Add to that the massive plot holes and bad acting and you get a recipe for failure.
While the main character is the absolute repository for bad ideas you'd be amazed at how stupid the other characters can be, it's as though they all want to die. For example in one scene zombies flood into the area, this is followed by one of the characters running TOWARD AND PAST the horde of zombies, followed immediately by the protagonist. Naturally these flesh hungry zombies let both individuals pass without harm after all we're watching a terrible movie.
All of this hullabaloo because she needs a zombie alive. Following this massive plot hole what does she do? She kills the one she wanted alive.
This movie is garbage don't bother watching it, I'd watch a 100 hour marathon of The Wiggles before I watched this again.
