If you are going to see a zombie movie set in an apartment during a zombie apocalypse, I would recommend these movies instead: Alive (aka this movie but better), The Night Eats the World or Rammbock: Berlin undead. They have more fleshed out characters and a more believable storyline. It felt to me that the main character in this film had almost stunt double level physical strength and his love interest had no abilities (whatsoever) to protect herself. She was only safe because she was of value for him and he spent all his time and energy trying to save her with little effort from herself to save herself. Also they gave her no backstory?! So it was a boring and unrealistic "Save the Girl" story instead of a survival story where two people partnered up to save themselves and each other and fell in love. Three stars.
