there are two bandwagons at work whenever a band gets successful, or changes their sound
1/ those who suddenly jump on the repect bandwagon and become huge fans
2/ those who suddenly jump on the diss bandwagon because they're the original fans.
both are normal behaviour. it is sad however that the latter people want the prodigy to be stuck in the rave era. as someone who really was involved in the UK rave scene from day one i have to say the past belongs in the past. similarly prodigy's old stuff comes from a different time, with a very different atmosphere and perspective. I respect liam for not coming out with FOTL 2 immediately. he's stuck to his guns and only announced a release when he's happy with the stuff he's been recording.
but to judge it before you've heard it suggests a certain amount of myopia on your part. you are stuck in the past, closed to the future before you've even experienced it. maybe you should curl up with an oasis record... they never change, and release albums pretty regularly.
blind faith perhaps, but in your case it'd be blind, deaf, dumb and faithless.
