I have friends in the Southampton Oceanograhpy Centre (SOC) that do a fair amount of climate research / modeling.
and well they go along with the whole film is flawed thing. and that its really only fiction.
From what i've seen from posters and trailers and such imho it looks like a load of rubbish. But then i am a scientist and so wont fall for the extendid scenes of peril etc. and would be sat there the entire time pulling faults in the story.

Regarding the whole salinity thing and the ice caps diluting the sea water is rather unkown and an option. As if you get salt water cold enough its still going to be that salt water. Although some of will fall out of solution alot of it will remain.
As for the whole tidal wave thing, that would have to start off fairly near the coast of america as the wave itself will decay rather rapidly.
Another thing i remember having a discussion about is the whole sea levels rising thing due to ice stuff melting. As per bouncy thing to get somthing to float you must displace an equal amount of mass of water below the surface to float the combined weight.
As most of you will know the density of ice is lower than that of water.
If all the ice in the polar regions were to be melted the mean rise in sea level will be next to nothing as the amount of volume of water increased / the surface area of all the sea's is rather small.
In the order of mm's i think if not less.
