I agree and disagree.
First off the characters save the new director are very human and well written.Gibbs isn't a Jerk,he is one with a Heartof Gold
and he's a great judge of character,plus considering what the guy has been through. But Mark Harmon is a terrible actor who makes everything Gibbs says sound wooden and lightweight.Any competent actor would do him justice
Tony is a Jerkass but very funny,this actor does him justice I love how he's always referencing movies and makes a great comic relief.
Ziva is great foil,and the actress is great,but doesn't look the part and the cliches of the Middle East are embarassing,but honestly Cate was better
is a great character,by far the most human of the crew,and by far the nicest,but Sean Murray is a little wooden [but not horrible like Harmon or Rocky Carroll or especially Lauren Holly] but still pretty good at making the right Flat What
Abby and Ducky are the two best characters,the quirkiest but most developed and the actors do their characters the most justice [also Pauley Parrette as a degree in Forsenics].
The guest characters almost never can act,they might as well be in The Last Airbender
The characters are great,it's the plots that suck all of them save one occasional one have a Dead Marine and Gibbs is never wrong.Every time they go foreign Tony becomes an Eagleland Expy and the Americans always end outsmarting the others [see the Mexico and Israel epsiodes].The whole thing is so predictable
And the set is atrocious,it doesn't look like it's in Washington DC and they don't hide it well at all,Stillwater Pennsylvania looks like an LA suburb,and the egregious examples only get worse.
However the twists are usually pretty good,the two parters have great cliffhangers,and the acting [save Gibbs] is actually alright.
All and all it's run of the mill but at least it doesn't go overboard with the wacky promos like CSI.
I'd give it a 6/10
