auroraparadox: On further thought I would also recommend Miss Fisher's Murder Mysteries. The story lines are good and the violence isn't over the top.

However, Miss Fisher herself is a bit on the promiscuous side but nothing is shown on screen.

Matewis: I saw Tour of Duty as a kid and thought it was very good, in a disturbing sort of way. Anyone know if it is actually any good? Perhaps not ideal though since I definitely remember it as being quite dramatic.

Less dramatic but still very good from my kid eyes back then : Counterstrike and Bugs (though how difficult these are to get hold off I don't know)

pmcollectorboy: Baa Baa Black Sheep.

OdanUrr: Well, I'd start off recommending JAG, the series from which NCIS was created and, incidentally, one of my favourite series. Ever watched "A Few Good Men"? That's JAG in a nutshell.

British crime dramas are, in my book, some of the finest TV you'll ever find and I'm glad you already got recommendations on Morse, Lewis, Endeavour, Life on Mars, New Tricks, Gently, etc. All of these are definitely worth watching. I'll also throw in Agatha Christie's Poirot (with David Suchet in the titular role) and Miss Marple series. I'd be remiss not to mention Sherlock Holmes. Here you have the 1984 series, starring Jeremy Brett, or the more modern adaptation with Benedict Cumberbatch and Martin Freeman. The US made its own version (as they usually do, often poorly) called Elementary, which I'd only recommend watching for Lucy Liu (Jonny Lee Miller isn't too bad as Sherlock). It is a tad too procedural for my tastes though, and each season has way too many episodes. If you don't want anything too dramatic, I'd counsel to stay away from Broadchurch and Luther (even though they're pretty good series in their own right).

Back to the US, I'd probably recommend The Mentalist and Psych. Curiously, they share a similar premise in that the main character is highly observant, what allows them to solve crimes in their role as a consultant to the police. In The Mentalist, the main character, Patrick Jane, used to be a con man who pretended to by a psychic. In Psych, the main character, Shaun Spencer, poses as a psychic in order not to get arrested by the police and it spirals from there. Psych is by far the more humorous of the two, dishing out pop culture references left and right.

Oh, yeah, and before I forget, you also have White Collar, a procedural about a highly talented con artist who's hired as a consultant by the FBI. Has a very Ocean's Eleven vibe.

amok: oh, and two more US TV series which if found quite good

Medium - [url=https://en.wikipedia.org/wiki/Medium_(TV_series]https://en.wikipedia.org/wiki/Medium_(TV_series[/url])

The Mentalist

edit- sigh... bloody gOg forum software messing up links again...

LongitudinalThrust: Almost no violence; the detectives find the bodies, they don't make them.
Humour is... well... British. Not the slapsticky Monty Python/Dr. Who kind, subtle British, mostly based on the characters quirky personalities etc. I know, bad explanation, but there isn't really a North American equivalent of British humour that I know of.

If you're looking for more light hearted North American style I'd suggest a couple of Timothy Hutton shows:
Leverage - kinda modern day Robin Hood type stuff, think A-Team but hold (most of) the cheese.
Nero Wolfe Mystery - basically 1920s Amercian version of Sherlock Holmes.

If you want older military, here's a Vietnam hospital based one:
China Beach. - basically MASH, but much more on the serious side.

Edit: Woops, didn't notice Matewis already said Tour of Duty.

RWarehall: In terms of crime series with humor, I'll second Psych. A somewhat similar series is Monk who is an inspired detective who is rather OCD.

For firemen there is Rescue Me. Plenty of humor but can be pretty emotionally gritty too.

jonwil: Diagnosis Murder is an excellent older crime/detective series and its not too violent or dark IMO (not compared to modern shows)

adamhm: Person of Interest

gandalfnho: In what terms you compare Leverage with A-Team? Does have some humour at least? A-Team is a series we like here at home.
And how much serious is China Beach compared with MASH? MASH was comedy, but had some darker moments too.

gandalfnho: How's the seriouness of Medium?

gandalfnho: Too gritty? Normally I prefer something more in the light side, especially to watch with my parents.

gandalfnho: What is the disturbing part? Blood and gore?

And the other two looks interesting, one has even the guy from Manimal.

tinyE: Anyone remember "Tour Of Duty"? I don;t think it even lasted one season but it was a great show and a tough one to make, about the Vietnam War.

Matewis: Ahem..

tinyE: I edited my post. :P
