I was also at Friday's show (also my first Bruce show ever) but had the opposite reaction. I had a great time and thought the energy he brought was awesome and he put on a great show, one I will never forget. It was a crowd mixed with many age groups, in my section it ranged from the 20s to the 70s, but most were on their feet all night dancing and singing.
And he has been closing the shows on the tour a set of songs in the encore, Fridays starred with Born to Run. Most shows end with Tenth Ave Freezeout and I'll See You in my Dreams, this show was no different. And no, he wasn't begging for more encores, that's how he ends his shows.
Sorry you didn't have a good time, I would think you're probably in the minority there. If I wasn't going to the RU game today I'd be tempted to go see Bruce again tonight.
