I am sure of the point of Lost Tales (to explore the Babylon 5 universe for fans who dearly miss the series, like me), but I am not sure of the point of the 2 stories they chose to do. These stories are independent stand alone stories that do not add much to the canon. The first story focuses too much on religion, which I think, goes away from the main premise of the Babylon 5 series of keeping a neutral ground when exploring multiple cultures/beliefs in a highly diverse galaxy. The second story, makes the great Sheridan seem like a easy target for technomage manipulation. Sheridan is a seasoned veteran of wars and the President of the everything, but seems to be easily swayed by a few dreams which I feel undermines the experience and greatness of his character. Yes, you can argue that the technomages knew he would continue to choose the right path, but, just having Sheridan hesitating makes him look so weak.
Anyway, I don’t want to attack something I appreciate. Regardless of its flaws, these stories are welcome and it is quite nice to revisit the Babylon 5 universe. In fact, whatever J. Michael Straczynski wrote Babylon 5, regardless of the quality,would have kept me quite satisfied. The series ended before its time and unfortunately, they could not hit with a spin-off as the Star Trek series did.
Lost Tales is a sweet addition to the Babylon 5 series, but the stories do not necessarily add much to the canon and therefore seem to only appease die hard fans who miss the series who need a Babylon 5 fix now and then.
