This movie dragged on for far too long. Honestly, unlike most,I did not see the end coming, but, like most, was confused as heck anyway because it raised more questions than it answered. The couple was rather annoying and unlikeable. I actually started to look forward to seeing their demise. Irritatingly, despite KNOWING what will occur, the guy doesn't try in any major way to stop it. ONE HUNDRED times!!!! Never explains anything satisfactorily to his girlfriend, never makes a concerted effort to alter events (well,once, when he just convinced her to stay in the room all day. Insert eye roll).
