I haven't been able to get into a NIN album since 1997. It just got too... "slick", overproduced and non-original sounding to me. There's a few gems here and there beyond The Downward Spiral, but overall it's trash to me. Also, once Trent decided to do the soundtrack for Call of Duty, I pretty much wrote him off as a sellout (in a bad way, to the pigs... and even worse to the war pigs). He got cheesy.
Kind of like comparing Metalica's Garage Days Revisted to their newer stuff where James H. decided to start doing a lot of cheesy "Whoa... whoas" and the music got all slicked up and overproduced along with it. It got cheesy.
They got old and lost their edge and started to smell like cheese. It happens. For me, it doesn't really take away from their old, amazing stuff which I still listen to and love:
Sometimes I think Metallica was simply born to do old punk cover songs:
