Rereading my past favourites is a very disappointing experience.
I've been reading scifi/fantasy for almost 40 years. Lately, I've been rereading some of my early favourites. The experience is almost invariably disappointing. This made me doubt my recommendations to people over the years. Is this feeling common? Should I even bother rereading stuff or just keep the fond (partial) memories of the first reading? How do other people handle rereading?
(To be more specific, I reread The Helmsman by Bill Baldwin, Heechee books by Frederik Pohl and even The Forever War by Haldeman seemed emptier, thinner and ending less heart catching.) I am now afraid to reread Scalzi's Old man's war books and Card's Ender series. I love them too much to risk spoiling the memory.
