I can't fully recall all of the segments in VoH, so I suspect because of that it is less effective than some of the other anthology films around at the time. I do recall liking Terry-Thomas and Glynis Johns in the 'Meticulous Man' segment - some rather dark humour there.
The Anna Massey 'Vampires' sequence verged towards parody a little. The Tom Baker 'Dying For His Art' sequence was the one I found most memorable. The Curt Jurgens segment I have always found a little tedious and I can't for the life (or should that be death in this case?) of me recall much at all about the Michael Craig sequence. So I gues my summary would be, "Good in parts..." (No, that's NOT a pun on the outcome of one of these sequences.)
