As for LotR; that had even less of a chance. All we got was some rumblings of some new (or possibly very old) race on the prowl who may or may not have been as scary as their servants like to claim (conspicuously loudly, one might say) and some scraps of hints of double dealing from within the rangers. We had about as much clue of B5's potential by the end of 'The Gathering', no?
You can’t seriously be suggesting that jms does not understand the importance of writing a strong, entertaining stand-alone pilot to a new series.
The problem with Legend of The Rangers was not that it was the first part of some epic tail that we (the studio and network) should accept on faith would become another classic. It wasn’t because of dodgy scheduling or low budget. It was because it was unimaginative and frankly not very well written.
Assuming that jms would have wanted the series to have been picked up – and since by then he was both an
experienced executive producer and television writer – he would have created the best standalone story he was capable of. If it wasn’t then why bother making it.
It was not very good. Which does at least lend credulity to the suggestion that he’s told his B5 story and doesn’t have a lot left in the tank – as far as Babylon 5 goes. Why is that such a difficult idea to entertain. It doesn’t mean he is talentless, it doesn’t mean he’s washed up as a writer, it only means he’s told that particular story, sold the scripts and a few behind the scenes do-da’s and it’s possibly time to move on.
