It's laugh-out-loud BAD. The script, acting, plot are all woeful and my 12yr old could have done a more convincing job with the CGI. Most of it is filmed on the real Queen Mary which is now a hotel in Long Beach, Ca or in a concrete bunker, sorry, "engine room". They hired about 20 extras from the local homeless shelter by the look of them who wander around aimlessly or fall over their own feet during "action" sequences. There is some preachy stuff about global warming backed up by bogus "science" and a 800mph tsunami (that's faster than the speed of sound folks!). I hope this movie was released as a joke but fear it wasn't. But seriously, if you haven't seen it yet then please do so because it's hilarious and you'll have lots of fun spotting the glaring errors, continuity bloopers, wooden acting and super-low budget production. It's so bad it's good.
