coming from a 4yr veteran of the USN i loved it. coming from an old school battleship perspective, i loved watching WWII based ships annihilate modern arleigh-burke class destroyers even though they were using some some sort of alien tech. i was a little disappointed that iona was a sub instead of a surface ship, but all of the naval combat was based on sound theory (excluding the gravity cannons and klein fields ) the anime had a good story line, great characters. my biggest disappointment however was that the origins of the fog, and their technology was never really explained at all. hopefully there's a secondseason in the works to remedy that and show humanity fighting back. (if there is and i haven't heard of it yet please let me know.)
