this movie was overall one of the best movies i have ever seen. It had not only GREAT actors but i also love how it all made PERFECT sense in the end. I LOVE how space and ocean collaborated to make the easiest movie to understand. It was SOOOOO realistic. Two thumbs up. Oh, and the opera music during all of the most suspenseful scenes? BRILLIANT. everything about this movie was truly worth the 1.75. Whoever gave this movie a one star is mentally impaired. this movie was TOTALLY worth the extra 4 stars. i srongly recommend buying this movie and watcing EVERY DAY:) it changed my life. watch and you will see the pure epiciness of this movie.
