Well, if we can't have JMS running Doctor Who, this will do! Anyway, with Russell T Davies returning to Who, good times are (hopefully) ahead!
Thing being, B5 has already influenced so many things, from ST:DS9 through The Orville to the Mass Effect trilogy and even the Trek reboot (far more realistic than the original). One only wishes that JKR had channeled B5 instead of Trek for Harry Potter! A well-done reboot with new sotires, charactrers and arcs might well do the same with future projects. Any potential improvement in quality has to be good.
Tantalising thought. Davies was interested in a Doctor Who/Enterprise crossover but it never happened. Given that JMS has expressed an interest in Who, might there be a possibility of seeing the Timeless Child walking the corridors of the last, best hope for peace?
