Loved it! Was on edge from start to finish. Excellent performances from many of the cast. They all play being scared well. They did a great job introducing the various characters and I felt for them (the staff, guests and terrorists) throughout the film. Very thought provoking and was hard to stop thinking about the film after I left. My husband found it more disturbing than I did. It was not a relaxing film but it was my type of action, emotional film.
