This might be silly to say this but "Prince of Darkness" for me is a masterpiece for following reasons:
- A seamless combination of supernatural horror with science fiction, that's not easy to do
- Heavily moody and atmospheric horror movie that grabs me by the balls.
This movie is a B movie but it is much better than any other big budget horror movies. There is surely a certain silliness to this movie but the mood and atmosphere, the direction by John carpenter transcend all of those.  John carpenter is like a teacher in "How to make horror sci-fi movie class", he is teaching us that what is most important in horror movies is not gore but it is the atmosphere and the suspense.

Prince of Darkness is a masterpiece

“ unease & Dread “ Mission accomplished.

His own soundtrack is a masterpiece in this movie.

It is pity that John carpenter is critically being underestimated in US. He is one of the most exciting things US cinema offered to the world.

Although not his biggest commercial hit movie, Prince of Darkness has always been my personal favorite from John Carpenter.
I was lucky enough to see it on the big screen when it was first released, as a Christian, it creeped me out and made me think.

Prince of Darkness, which I rented on VHS, was the only film I ever had to stop 30-45 minutes in. I had to wait to watch the rest in daylight.

John Carpenter was quite the rebel and a master of his art. Even though he is retired from directioning, his work will still be around. He has achieved immortality.

Leaves you disturbed and confused when you thought its gonna be campy... JC wanders off into deeper darker places. Clever bloke

In regards to Mr. Carpenter's remarks, I personally gravitate toward films like this where there is overwhelming dread. Invasion of the Body Snatchers and the cold war film On the Beach are among them.

Actually this film was a small hit back in the 80's. It had a budget of 3 million and made 14 million.

Carpenters best score

Definitely one of my favorite horror movies!✨

I remember watching this film for the first time as a kid.  It was on home video.  It definitely holds special place in my heart.  To this day I feel his 'Apocalypse Trilogy' (The Thing, Prince of Darkness, and In the Mouth of Madness) are my favourite horror films.

this movie creeped the blank out of me

"This is a message from the year 2029, what you are seeing is real. This message is sent as a warning. What you are seeing is real. What you are seeing is real. What you are seeing is real."

This is my second favourte Carpenter movie, second only by a fraction to "The Thing". To this day it gives me existential chills like no other film I have seen.

great movie still looks really good especially the dream sequences

If you read the end credits on this Donald Pleasance character is named Father Loomis a nod to his iconic Halloween role.🎬❤️

This move scared the crap out of me back in time because I knew also a thing or two about quantum physics mixin it it with religion made it so much more based on reality that's made it way more scary.
The soundtrack is mind-blowing it still hear the CD from time to time it sometimes gives me goosebumps.
