I don't really look at it as disappointments, more a case of the typical inconsistency that has watermarked their career.
* seemingly endless and gratuitous remixes - why?
* miming on TOTP etc after years of refusing to sell out - understanable but unpalatable all the same
* backing tapes rather than sequencers - lazy
* the need for Bernard to introduce every song these days - why?
* over-reliance on "greatest hits" live - given the increasingly hardcore audience there is surely no need to pander to those who only know certain songs? We want to hear different stuff, not Blue Monday, True Faith and BLT!
But the main one is the compromising on the earlier policy of mixing the set up every night. The rationale behind this decision of theirs is well-documented and understandable if not appreciated, but it wouldn't really hurt them to learn 25 or so songs for a series of dates and really mix it up a bit. I think we'd all prefer a wider setlist variety, rather than living up to their name by playing the same 15 songs more often than not, with subtle changes like swapping tracks 1 and 2 over......
