Recently went to a service performed by an Anglican minister, and there were actually quite a few witnesses there too (it wasn't in a church, not that it should matter).
I thought it was an excellent service (a few key scriptures and lots of interesting remarks about their life)
Of course many of the witnesses criticized the whole thing, for not focussing on an earthly hope etc.
My impression was it was far better than what you hear in a Kingdom Hall.
