Pack a Lunch
I'm not sure if it's boring, but, at 4.5 hours, it's long-winded.
And, without a narrative thread, you'd better love Hellraiser, and a stream of information coming at you, slowly, otherwise watching this will be hard work.
At 3 hours 11 minutes, I'm tapping out, to write this.
It's rarely insightful; very dry; and, one interviewee after another says, almost, the exact same thing, as the one, prior.
Apparently, there's another version of this, where 2 hours is spent on Hellraiser and an hour-and-a-half is spent on Hellbound.
Well, like I said, it's just gone 3 hours and I'm out; but, analysis of the 1st film is yet to cease.
I just can't take another minute of directionless talking heads.
