"Saying "This looks like it was made for television" is an efficient way of pointing out what's wrong with a movie without the need for further explanation.

That may be true of the ones airing today, but the TV-movie was a different beast forty years ago.
Horror has, for the most part, lied in film more than in television history. Although, this changed in the 1970s when TV was becoming more popular and more diverse in genres.

For two decades starting in the 70s, one could turn on their television every week and experience some great thrills."
