Fortunately I discovered their music in 1983, which means that it didn't take me long to then go through their back catalogue. We are all commenting because we care but one thing that I, and many others, have learnt over the years is that U2, as a unit, are tough. Tough enough to absorb criticism from their own fans because they know that expectations are increasingly higher with each release and they simply cannot be anything less than superb. We expect a lot and they know that, which is why they will, again, exceed our expectations. It's in U2's nature. Always has been.
