The book study was a great meeting, we hosted it on a 6 month rotating basis and it was well attended some people came who did not attend the kingdom hall. Yes people were sometimes demanding and thoughtless and did not appreciate that it was someone's home as well as a meeting venue. I think that they were more relaxed, social and informal than the main meeting and therefore somewhere where people could ask questions and be treated less judgementally.
The introduction of family worship night turned an opportunity for warmth and fellowship into another stick to beat the flock with. Gone was a one hour meeting and in it's place a demand to spend the whole evening studying watchtower approved materials.
