My j class experience last week was all positive.The crew were amazing, very attentive little things like replacing empty water bottle with a couple of new bottles while napping.They were even good for a few restaurant recommendations (which were all excellent

They do retreat to galley after meal service and dim cabin lights but every so often they will do a walk through to check on waking passengers.

I thought the food was good the portion sizes were fine by me

Pre flight drinks and hot towels were offered.

Lots to watch on in flight entertainment.
