Having just watched RIVERWORLD for the third time, I am very impressed with it. It got me to read the book, which I have been meaning to read for 30 years anyway. The 2010 version is the best, but the 2003 version is not bad either. Both were SyFy pilots that didn't get picked up, but both were well worth watching. Neither pilot seems to follow the book exactly, but given that there were a series of Riverworld books, the made for TV movies might have come from material that I haven't seen yet.
