I had a right laugh watching the Exorcist. Comedy gold.
I haven't seen this film since my younger years and I suspect much of the 'fear' was the mystery around it...before I disregarded stuff like that and the internet put many myths to bed (although tbf, it's probably created ten times the amount now).
Watched a bit last night and thought it had the amazing 70's cinema feel to it (you can also see where John Carpenter pinched some of the scenes in Halloween from....the prosaic early evening Halloween streets married with a piano motif and sound design).
Was it the more the 'demon/possessed' scenes which looked a little off?
