Lucked out with the blizzard on this quick trip to New York!
United's shiny new 787-10 Dreamliner with the new Premium Plus (premium economy) cabin is a pretty good seat, just don't think about the fact that it's much closer to what a regular economy seat was 30 years ago, only now it's an upcharge. Recline isn't bad and the leg rest, at least in bulkhead rows, adds a lot more to comfort than I expected. The in-flight entertainment has a nice screen, but currently the selection of stuff to watch seems pretty limited; hopefully that'll change in the future?
Note that rest of the amenities are regular economy as expected, which may change-- until 30 March PE is being sold as regular E+-- so this is not a full review of PE.
