This was a waste of time. Had promise but was confusing and the ending was very poor. Considering there was only 4 actors it could've been better. Tried to build up suspense but fell flat on its face with a confusing storyline. Had a slight twist but not enough to warrant the time spent watching the movie. Very disappointing. Only saving grace was a good looking bloke who was exploited showing off his muscular body, that was the most excitement of the movie. Will not be tuning in for a sentinel 2 that's for certain. Could've at least thrown in some massive sharks to keep us entertained, but no.
