I have watched and enjoyed the NCIS, NCIS Los Angeles shows, but the NCIS Sydney one is difficult to like. The lead actress, Olivia Swan who plays the character as gruff and tough but is really very grating on the nerves to watch. The character 'Blue' is deplorable, not very believable. the rest of the characters are okay. The plot though, is very US orientated and not much on the Australia aspect of things. Too bad, it might have had some potential.
As an Australian, so far the first episodes are cringeworthy. Insisting such common stereotypic misconceptions about the local culture and portrait just shy of fools, while playing up the American superiority over all things, it's going to be a hard sell to wait for this to hopefully get to the storyline and entertain.
