Q: I highly recommend the time to read "Foundation"...it just may convince you to continue on with the rest of the series. I believe it was the forerunner and main idea behind the concept of a galactic empire as has been expanded on by Star Wars and Star Trek. If you would like to see the genesis of the idea behind those phenomena then you'll very much be rewarded by reading the Foundation series...besides, anything by Asimov is worth its weight in gold and this is the zenith of his space operatic writings!

A:
Positive
