A great action packed film with griping performances and nerve wrecking moments spread all over it. A true break from dirty periodic war drama movies into modern day strategic sub battle with amazing vfx. The only dissappointment i have is that why I didnt see it before, if I had i could then have certainly seen it more than once as now it seems to drift out of cinemas i guess. To the guys who may complain that its another America saves the day kind of stuff, I agree the script could have ventured into an unkown territory to try to experiment but then it may have been a disaster altogether. The movie delivers more than what the script offers it so .. All in all ... A Fantastic Adventure...one that must be witnessed ...
