Like a lot of series 3 there are some germs of good ideas here and with a bit more work it could have been a much better story than it turned out. Thanks to Close Encounters of the Third Kind, UFOs and UFO hoaxes were a hit with the public at the time so a story that touches on those themes was probably inevitable. An episode that disappointed me I'm afraid as it doesn't come close to fulfilling it's potential. Even Lindsay Wagner seems to be struggling to muster much enthusiasm for this one. And even by the fairly low standards of seventies TV, the special effects in those episode are excruciatingly bad and cheapen and demean the whole thing. A great shame and hard to view this as anything other than a wasted opportunity.
