NCIS is a great show. It isn't a copy-cat show and is definately unique. I like how it is "navy" based and the characters are quite entertaining. One thing I absolutely love is how at one moment, the show can be all serious and then the next comes some comedy relief.
I think NCIS is a great show. It certainly is unique. It can be very funny and then very harsh. But what I like most is that the characters care about each other very much -- even though the opposite seems true.
