Outside of the universal feelings towards Pablo Honey, Amnesiac and Hail to the Thief are the two that some fans seem to have problem with. I personally have always been surprised that someone could not like one of those albums, or both, but like the rest of their work. Neither feel that much different than anything else they've done to me personally, but it's admittedly hard to look at those albums subjectively at this point. I'd understand a distaste towards Thom's solo album far before either of those two, as I think it's a bit weaker than anything the band has done other than Pablo Honey. That said, I still like it as well.
In the long run, we all have different tastes and opinions. For most things, I couldn't even begin to try to explain why I do or don't like things, I just do.
