Re: Smallville Season 11, it"s happening...
I know this is slightly off topic, but one of the best SF novels I ever read dealing with time-travel (sort of) was James P. Hogan's excellent Thrice Upon a Time
. I realize it would be considerably dated by today's standards (written in 1980) it was thought-provoking nonetheless.
