Nobody understood the Revelation book. And if you did pick up anything from it, it is now "wrong".
Meetings are not animated, entertaining, and if you get a monotone speaker or one who is wordy it is even worse. For kids and people who work it louses up the sleep.
And it is not 1 1/2 hours, you gotta dress up, travel, be there 20 minutes early for duties (remember no rules). Same for service, waste a whole morning and call on 2 or 3 people, then spill McD on your tie. Rember the comment about doing family worship for 4 hours? Because that is how long it used to take to do a bookstudy.
