You may, as many of the reviewers before me have, argue that this episode is just about the worst episode in NCIS history, and I can understand where you would be coming from as this was highly unreaslistic, but compared to this season's premiere, or the third episode of the season, this episode was a thousand times better - and that is irrefutable.
Things I Liked About This Episode: I firstly really loved seeing Eric Allan Kramer as a Guest Star, as he is a spectacular actor on the Disney Channel show Good Luck Charlie, and I thoroughly enjoyed watching him in a polar opposite role. His acting was great, and I definitely would've loved to see more of him.
I also liked to see Ducky dating, although perhaps it would've been a bit more believeable if he hadn't been doing so online.
Also, the case was definitely very interesting and highly enjoyable, even if the ending wasn't so.
Things I Disliked About This Episode: The most obvious thing is that the storyline was extremely unrealistic. I have not heard of a more preposterous motive than to create an interesting case for a Medical Examiner whom you are dating. It was really over-the-top and unrealistic and quite a lot stupid actually.
While I didn't think much of the motive and the conclusion of the episode, I thought the case itself was spectacular. If they had a different killer with a different motiev, then this would've been a beyond flawless episode, but as that is not the case, the ending of the episode was a significant blemish.
All up, I can't say that I am disappointed. I was very enthralled and highly interestied by the whole episode, except the last 5-10 minutes, and the vast majority of this episode was spectacular and flawless!
Keep it up, NCIS!
