The filmmakers apparently made no effort to maintain even the lowest acceptable level of technical/scientific/logical consistency. It was never explained convincingly why the crew abandoned the conn (was it the gas leak? if so, why didn't they put their gas masks on?) effectively losing all control over their boat and fate, the procedures presented are way off the mark, the exhausted, asphyxiated crewmen find the energy (and the oxygen!) to cheer at the end, the conning tower diving planes have miraculously broken through the ice without leaving any trace (they are much wider than the trough opened by the sub), etc., etc. A waste of time and money, both for the makers and the viewers. Only thing worth it is Gabrielle Anwar (mainly because she is very agreeable to look at).
