I just want to say the acting from the two main characters was incredibly good as well as the acting from the security guard, I think they've been in a lot of movies so they have experience but the couple waiting for the elevator were awful, worst acting I've seen in a long time no idea how they got the okay as it compromised the film. The concept was good but the way they went about it was not the greatest. I just feel like it could have been done a whole lot better but still I thought it was alright, definitely not bad at all.
