I too have fond memories of this show though I recall its budgetary limitations being obvious even by then-contemporary standards.
The lake monster in DEAR BELOVED MONSTER looked like a briefly-glimpsed head of cabbage. But then so did the 'revelatory' 1970s photos from the underwater camera at Loch Ness.
One interesting episode was A GAME OF HEARTS. Darren McGavin plays a heart surgeon who takes a heart from a not-quite-dead donor. He then starts getting chilling phone calls from the dead man. The final scenes have him fleeing through a deserted house with his undead tormentor in pursuit. It was shot in very NIGHT STALKERish style.... substitute the donor, with a black and bloody hole in his chest, with Barry Atwater and you're pretty much there. And the character's name? Gabor Skorzeny. The vampire's name in the NIGHT STALKER TV movie? Janos Skorzeny! Hmmmm..... well imitation is the sincerest form of flattery I guess.
I would certainly endorse another look at THE EVIL TOUCH.
