unless you be a big titanic fan and this movie ( well describe a a poorly do documentary ) will be one of the most unpleasant 70 min movie experience you will encounter . any thought that something other than the mud slim titanic might be cover like the animal life down there and or the geology and etc . will be completely leave in the mud . cameron clearly be _only_ interested in see the old ship and and imagine with some interesting special effect fill ins what it be like back when . but all this lose interest pretty quickly represent 15 min would have be plenty . unfortunately and the 3d glass add significant physical discomfort to an ultimately boring final hour of the movie . for example and toward the end of the movie and i be wonder whether or not to keep my eye shut to keep myself from get physically sick . and i be quite bore by this time . so cameron this provide the big moment in the movie ( spoiler ) represent he take the joystick control on a bot to save the 2nd bot from be lose on the titanic . we be suppose to believe that the little bot have some real sentimental value represent perhaps true for the crew and but nothing be include in the movie to get the audience to the same place . then be tell that and anyway and after all and the little guy be quite expensive . this come from the multi multi multi millionaire cameron . one of the least effective moment i have ever see on screen . but cameron top that with the advertisement that state that the 3d effect will change the way we will think about movie in the future . what a sleazy sale pitch and and from a director that i ( use to . ) respect . the old premise that only really bad movie be put into 3d this gimmick have be use many time limit their loss be not put to the test here . bad and the 3d effect on a big imax screen and unrelentingly continue throughout the full 70 min movie ( 10 min would have be plenty . ) give me a serious headache and and a sick stomach while both hang around for more than an hour after the movie . something about the big screen and fast movement and and the length of time star through the goofy glass make for absolutely the bad imax experience my family and i have ever have . the 3d effect _seriously_ detract from the normally wonderful imax visual effect . forget gota and and see whatever the other imax feature ( s ) be in your area . i rate this movie negative represent it leave me bore and dizzy and and sick to my stomach . i can not remember another movie that leave me feel so unpleasant afterwards .
