I actually really enjoy the way the Mandalorians are depicted in The Clone Wars, and prefer that depiction over all others.
Lets look at it this way, you have an entire culture that has overcome its violent past and is trying to move forward and not stoop back down to that level. Perhaps the pacifism is too far of a pendulum swing, but I think it makes the situation for the Mandalorians very interesting. They are so much more than just warriors, its a living culture with so many other facets. We see their architecture, their art, their medicine, etc. You also have the Death Watch, a group of terrorists who embrace their warrior past as part of their heritage. They are nationalist, extremist zealots that seek to bring back the days of Mandalorian conquest and plundering. Its not something to aspire to and makes them just as bad as the Galactic Empire. I also like that there’s less individuality with them in terms of their armor. I know lots of people like the idea of the Mandos wearing an assortment of different colored armor, but I like the idea that they are more of a traditional army. I think the idea the Death Watch represent in the show is a nice one to have in Star Wars.
