First of all I was surprised not to see a longer list for this clunker of a movie. The things that bothered me most:

Bad guys have those jet skis, no shortage of gas, because they have a tanker full of crude oil. So how do they make the gasoline?

Also, they seem to have an endless supply of cigarettes... and the earth has been under water for how long? Their ancestors must have had the prescience to rob a tobacco factory and seal millions of cigarettes into ziploc bags or something...
