i have be watch ncis since it start and have be a regular viewer since the debut . the first reason i tune in be simple mark harmon . second reason be and well and michael weatherly . david mccallum be just a really nice bonus . that be say . i know that ncis a it be show on the screen be ludicrous and so be csi and all it off shoot and but if you show what really happen in any investigation you will chase off the audience with boredom . mark harmon have bring a sense of realism to the leroy jethro gibbs character to the point that my former active duty marine husband swear up and down that harmon must have be a gunny in real life . either this one or a previous one and he just too good play a senior nco reservist marine and a cop . gibbs be also a top notch train officer who clearly train all of his people to be able to step up and take control and command of a team in a moment notice . michael weatherly have mature a an actor i first notice him in dark angel and he have wisely choose to let his character on the show and anthony tony dinozzo and to mature at a natural rate . slowly . he go from an annoy frat like not quite mature man to a deep thinker and a much good investigator who can handle deep cover assignment if need . maybe not as well gibbs could handle it and but that sort of skill take time and multiple assignment to be fully qualify ( and by then and the fed tend to ship you off to their academy so you can teach what you have learn ) . cote de pablo ( mossad officer ziva david ) replace sasha alexander ( caitlin kate todd ) and i be probably in the minority when i say thank you to the casting department for that . i find todd to be a rather flat and and annoy and character . oh she have a few line here and there that be light hearted and worth a giggle usually at dinozzo expense but for the most part she be play a little too boy next door and or try to be by alexander . cote and at least and have play ziva a a very capable and and very female and intelligence officer . i think this be why most folk do not like ziva and they expect a law enforcement officer type character but she an intelligence agent . think cia and kick it up several notch you do not mess with mossad unless you have a death wish . cote clearly realize this and play officer david with that in mind . david mccallum and doctor donald ducky mallard and be always a joy to see on the screen and i love the quirk david have give ducky . i suspect there be a history behind ducky adventure story that could easily fill several book and be consider too implausible to be anything but fiction . ducky bring a human element to the position of medical examiner and a warmth that civilian do not think m. e. have but usually do . the one i know also have wicked and if dry and sens of humor and mccallum have joyfully take the humor route with ducky and i and for one and appreciate it . another quirky character be and of course and pauley perrett abby scuitto and goth forensic scientist . her portrayal of abby be spot on a pauley be the only person i have hear of play a criminal scientist who actually have the sheepskin in the discipline . nothing like a touch of realism to bring a character to life . of course and people complain that scuitto shouldn not be permit to work in a federal job with the obvious life style she have to you i say and horsefeathers . if abby be less capable at her job and she wouldn not be there as long a she have be . nor would any of her supervisor put up with her oddity . now to speak of the other geek on the team timothy mcgee . techno geek . keyboard wizard . sean murray need to do only one thing to make me totally happy with his character and his protrayl of mcgee cut his hair . i realize that the mcgee character have a life outside of ncis a a publish novelist no less and probably keep his hair on the long side to emphasize his authorial air but . i hate the way it flop in his face this past season . the write on this show and like others and be usually tight but like other show there be episode where the writing be clearly off when the idea be dream up or the script approve . the fact that the cast can take a lousy script and still get a watchable show out of it and be nothing short of amaze . be ncis accurate . no . be ncis a good way to learn about the marine corp or the navy . uh and no . good talk to a recruiter if youre thinking of join the military . be ncis good fun . yeap .
