Micky Dolenz says there was a fundamental change in the way movies were made after the Monkees’ ‘Head’ arrived 55 years ago this week. 

Source material, much like actors, was merely a tool for Stanley Kubrick, a handy instrument to facilitate his vision.

I am in no way suggesting that these films were the best of this horror sub-genre. I am simply saying that, to me, they left a lasting impression.
