Why does everybody insist SOE is their 14th album? Rattle & Hum is a soundtrack album with both studio and live songs, and Original Soundtracks 1 is not credited as a U2 release, so technically you couldn't count that one either.
On topic, of course Pitchfork isn't going to give U2 a good review because they don't make music that is tailored to Pitchfork readers' interests. (Yes I'm that cynical.)
I would consider R&H a album, with 9 new studio tracks. But I get what you mean, it isn't a typical new U2 album big roll-out before the next tour kind of album.
I suppose starting with Under A Blood Red Sky U2 used to put out a quick release to tide fans over until the next big studio project.
So we got UABRS, WWIA, R&H, even Zooropa (a rushed and in-the-moment project-- that I wish they'd do more of sometimes).
After POP it was the beginning of The Best Of's, with the 80's and then after ATYCLB it was Best of 90's. It was only after that they appeared to break tradition (the fan club releases not withstanding).
As for Pitchfork, if the criticism is "they keep trying to sound different," it fails miserably. Because if U2 were sounding like U2 of days past, the criticism would be "it's the same old crap from U2." But if they keep trying to push themselves and challenge themselves to evolve, they get this crap from Pitchfork.
If however, their criticism is "they keep trying to sound different and the result is material I don't think is very good," then that is their opinion and they're entitled to it.
I have the feeling a bias is there to dislike anything the band does at this point. But hey, everyone has their own set of ears channeling this stuff and not everyone is wired the same.
Personally, I would like to see U2 reunite with Enos and Lanois and do a NLOTH unleashed -- really get experimental (but not Passengers experimental -- save for Blue Room) and let loose instead of worrying about a successful single for a change.
I think U2 is at their best when they are simply creating -- not creating with a calculation in mind -- which is what I think most of the negative reviewers assume with their latest outputs.
