I sat in 73J last night/this morning. It was not bad at all. It seemed that there were a few things missing: amenity kits, hot towels (which they seemed to stop providing around row 65) were the 2 things I noticed.
I had a seat mate and she got up once during the entire flight.
The only thing annoying was I reached up to stretch once and I touched someone who was just loitering by the loo. Not a big deal, but at one time I felt like someone was watching the IFE over my shoulder.
I didn't notice the tail wagging or anything odd. I would recommend this seat again.
