Meh. I would be happier if they had a large amount of controlled Q&A time. My favorite form of this is to take turns holding a proverbial talking stick, say 5 minute or 10 minute intervals, and the guy without the stick is obliged to answer the first guy's questions, and the first guy has the option to cut off the second guy and direct the conversation. Something productive might happen if they had that. IIRC, Matt is big for things like this. I wonder why it didn't happen. The other guy didn't agree to it? Makes sense. The pastor just wanted to deliver sermons instead of engage in discussion (as dobbie noted).
