The Beatles were simultaneously an AM radio pop band AND an experimental pop band. We've heard these records to the point that they've lost their element of surprise. The White Album, for example, is a really WEIRD record. Even the happy ditties on that album come off sounding creepy.
Therefore, though Paul is certainly talented, I have every right to view his solo career as a colossal wasted opportunity from an artistic standpoint. His accountant would disagree, surely.
