I loved Otherland. It's appeal for me was that it is so unique. Very rarely has an author created something which is so...ambiguous. The virtue of Otherland is not that it has some over-arcing epic story or is a journey through the soul of humanity(well it is in some ways), but that it brings to light the very thin veil between the real and the unreal. Which in our world is getting thinner and thinner all the time. I liked it.
