OK. I really enjoyed RFA but thoroughly disliked VALIS...I read it long ago and hated it so much so that I have vowed never to read it again. (I believe that VALIS is the only PKD novel for which I have ever had a negative reaction.) Anyway, my question is this: - are the two that dissimilar? If so, how so? ...or ... - have my tastes changed that much (obviously, feel free to speculate here)?
