From an empiricist point of view, remarkable coincidences time and time again at the conventions made going enjoyable and the book releases, some dramas, talks from old gb, listening for hints about the GT, looking at attractive opposite sex and searching for a mate, the experience of JW fellowship and closeness to God. Inspite of hours and hours of sitting down and listening and waiting for the program to be over, the heat, the unbearable humidity with rain and sweat and discomfort. An assignment made the time go faster. Im talking about the large conventions. It was an experience and you had friends and socialized and new members got baptized, they served food.
I honesty have to say that this last Patience convention was well done—take what you want out of it but it was easy to listen to and they kept your attention.
You also have to look at conventions as worship. JW worship involves listening to discourses aka talks and not rituals jumping up and down mumbo jumbo prayers.
