By the way, there's a pretty nice recent article on the topic by Steven Weinberg in, of all places, the New York Review of Books: http://www.nybooks.com/articles/2017/01/19/trouble-with-quantum-mechanics/

It would be nice to give you a link to a good technically-oriented overview, but so far I haven't found such a thing.

No worries! There is so much hogwash peddled as implications of quantum theory it's not too surprising anyone with real physics experience would tend to shoot from the hip :)
