Okay, I get that. I also think they're inconsistent, though for me it's more discography-wise. That is, the number of meh to bad albums possibly surpasses the number of the really good ones.
I'm still completely crazy about Passion Play and (mostly) TAAB and Minstrel. Songs from the Wood, Horses and Too Old, while patchy, are also quite enjoyable. Aqualung's quite hit and miss, so is Stand Up. Stormwatch is already a boring retread and I don't think I've listened to any of the Eighties and Nineties albums and This Was more than once.
That said, their 70's rhythm sections are, IMHO, absolutely astonishing and Martin Barre is a truly excellent guitarist, in fact, throughout the second half of their career Barre was quite often the reason to listen to the band at all.
