I quite enjoyed watching this one. It didn't stretch my brain very much, but there were a few reminders of other great sci-fi: Sarah Douglas was in Superman II and Babylon 5, The Tok'ra reminded me of Dax from DS9, and there is also a Babylon 5 episode that explores similar ideas too. Finally, the end of the first half reminded me of a scene in Buck Rogers, and I didn't mind that at all!
