I think it depends. I think if the mysteries are only resolved a la Star-Trek style technobabble, then yeah, no one would feel satisfied. I think part of the enjoyment of mystery fiction for most people is the relationships - like if Col Mustard had a motive to murder his wife, but the murder was actually someone from a rival company trying to frame Col Mustard. And we are seeing relationships and personalities getting fleshed out, so I'm not too worried about babble.
