Suddenly, Porcupine Tree

I have always been a Beetles, Stones, Springsteen, Young etc fan. You could throw in Yes, ELO, Pretenders, Dead and many more. You get the idea. I bought a porcupine tree album a few yrs ago gave it a spin and that was that. Did not get it. Recently I gave it another spin. Now suddenly I own everything they have done and starting on solo stuff. My favorite but not limited to, "stupid dreams". I now can not get enough of this band. What happened. Did I just get older? Like a "lightbulb sun" going off in my head. If you do not know this band get to know them. Anything I am missing? Other favorite albums of Porcupine? Other bands similar experience with?
