That would have been SO ideal!This is good news maybe even more than when they picked up Buffy. Angel could probably use the exposure even more. If they had really been thinking on their feet they would have started Angel S1 at the same time as Buffy S4. That way they could have played them in order with one Buffy and one Angel each night.
Unfortunately you are right and wrong, there are many sifi programmes and films with monsters that are obviously men dressed up and Buffy is in that category aimed basically at young teenager's , and Buffy was for 5 years until they joined a studio that had no decency committee which then allowed Whedon and Noxon ego's to run free and abuse their staff and trustIt would have been better airing on C4 on its original broadcast as I doubt it would be cut up into a sometimes incomprehensible mess as it was on the BBC. If you have to air a show twice in one day, cut and uncut, then don't bother acquiring the rights. It's not a children's show.
