I can appreciate the genius behind Foundation. It is well written, intelligent, and well developed, so it deserves it's "classic" status.
I found it to be slightly boring and dry and not worth a reread. Since it was a compilation of self-contained short stories, I found myself not connecting with the characters as much.
My daughter told me I really need to read "I Robot."
Characters can be boring because its not about few character like most series. Its about the Foundation through history. Mule was the only real great character. I think its more impressive that i can barely remember the character of the books except Mule and still the series is classic for its ideas,historical scope,world building.
