There'll be another attempt at Riverworld tonight on SyFy. Four hours long! I plan to tape it and decide later how much of I want to watch.
Probably unsurprisingly, the riverbank shown in the previews looks like areas around Vancouver, BC that show up in other SyFy movies, and the characters look just like some of the characters on BSG, Smallville, V, and other shows filmed in Vancouver. I love Vancouver, but I've never seen any aliens there. Must look harder, next time I'm there.
