IIRC, it's not actually vaseline, but a special lens. But everyone assumes it's vaseline so...
I never liked this, but watching it again recently I could sort of see what it was aiming it, even if it doesn't always succeed. It's really attempting to be a huge Tolkien-style fantasy epic, with a big range both geographically and historically. A truly alien planet threatened by a Lovecraftian malignant, cancerous growth. It doesn't quite work, but it's pretty much the only thing in Doctor Who that even tries this, at least on TV, so I guess it's worthwhile for that reason if nothing else.
