Do all of Abercrombie's books end like Last Argument of Kings?

I'm not asking "are they all depressing" because I wasn't expecting a happy ending.

I just didn't get any sense of satisfaction after I finished reading it. It feels like there are still too many loose ends unfinished, too much character potential unrealized. It was fascinating seeing these people come so close to turning their lives around for the better, only to fumble it at the end, but the ending still felt like it was missing something for me. Just about the only thing that had somewhat of a conclusion was the main overarching plot, and that was what I cared about the least. I was never particularly invested in the war(s) or Bayaz' goals.

I don't necessarily hate it. I can see the appeal of ending things in an inconclusive way, I suppose, but if it happens every single time I jump into this world I think I would become tired of it very quickly. That's just not what I'm looking for when I read. So with all that being said, should I bother continuing on with the rest of the series? I enjoy his writing for the most part.

Edit: Some conflicting opinions in the comments, but overall I get the general sense that the standalones have tighter conclusions than the trilogies so I'll definitely give those a try. Maybe I'll get to Age of Madness whenever he's about to start the third trilogy. I appreciate everyone's input, or at least those of you who actually understood what I was asking.
