My experience is that a talk is interesting or not depending on how much the speaker incorporates into the outline from external references. When he adds information and references it, this gives weight to what he is saying. It is tragic that there are influences around who seek to extinguish individuality on the one hand, and genuine desire to refresh, stimulate, and encourage the audience on the other hand. Innovation in other words. But then again, when an organisation at the top is dysfunctional, it can be disconcerting for those dysfunctional leaders see others do the right thing.
In my experience, there are few interesting talks given anymore. It's becoming a desert of sorts. The "famine in the land" is not really in the realm of Christendom as I was led to believe, but right there in the kingdom halls. The leadership of the WTS is addressing meeting attendance in the April 2016 edition of the Watchtower magazine.....
"REASONS TO ATTEND MEETINGS
They educate us.
They encourage us.
They bring us under the influence of holy spirit.
They give us opportunities to show our brothers that we love them.
They unite us with fellow believers.
Our attendance gives Jehovah what he deserves.
Our attendance shows Jehovah that we want to draw close to him and his Son.
Our attendance demonstrates that we support God’s sovereignty."
I can't agree with any of the above. It's just not my experience any more. I grew weary of RC ritual and repetition many years ago. Yet in many respects, WT meetings are becoming mere ritual and repetition and underpin the sovereignty of the GB, and neither encourage or educate.
