They Came from Somewhere Else

I remember this as a quasi comic strip presents. I do not understand why it was not repeated, and would love to see it again. It comes under my list of ten most interesting television programmes along with Melvin Braggs interview with Denis potter, prospects(which was also too short lived for such a great programme), Ivor the engine, danger man, the comic strip presents, edgar lustgarten presents(the un-americanised Hitchcock), the last resort, private eye(American one off mini-series pre-L.A Confidential/black Dahlia/mollholland falls) and filthy rich and cat flap(a television programme understatedly good as it had been honed after the young ones and the comic strip presents but maybe so forward as to never warrant a repeat ever(in fact, the BBC have never repeated it since it's original showing)).
