Whew… there are some big expectations with such a big name attached… Supposedly a catastrophic cascade of series of events and underwater crisis turns out to be relatively easy to envision – and moderately claustrophobic, dark (dark dark), rather suspenseful story; however, there are times that one can almost feel the intense panic creeping from within and crawling up, closing in, tightening, and throat–gripping, especially if one can relate –hmmm—more or less. To certain extend, of course. Nevertheless, can’t really say breathtakingly fascinating, but mesmerizing perhaps. Although mildly entertaining, and yes, at times captivating, however, it’s somewhat predictable. Outstanding cinematography though – ABSOLUTELY gotta see it in 3D. Don’t expect a top action speed thriller, but human drama and some terrifying adventure. At least there aren’t any underwater cave zombie-monsters engulfing our actors.
