I was initially turned off by the inaccuracies. Some of which I found glaring even knowing that there was no way that the Navy would provide any advice to a show about a sub turning on the U.S. even in the face of a possible coup.
Once I managed to try my best to ignore it or simply believe that the show is set X years from now after the Navy changed every policy in the books for no good raisin, I actually liked it a lot. Shame the ratings don't foretell a long future.
I will admit that I do think it possibly would have been better as a limited series with a fixed amount of time to take the story to its end.
