Like most of my reviews, I will try to keep this brief. I say watch it twice because as much as i love low budget movies...I couldn't decide if i loved the movie or thought that it was a waste of my day. After the first viewing, i didnt get a chance to see the movie again until 3 years later when i got a chance to purchase the special edition(before it became an excrutiatingly high price) i picked it up used from the store that i worked at. My first point is the awesome soundtrack. I actually purchased the special edition because of the soundtrack and the packaging. To pay $25 dollars for a soundtrack and a cool case is extreme, but that shows how awesome the sntrk is (as long as you love old-school punk). But after the second viewing I realized how incredible the movie really was, whether it was a for the simple great humor or the incredible satire that it is. You may want to rent it before you buy it, but when you realize that you love it...you wont feel that it was wasted money renting it first.
Ok, I will try to keep this brief. Hellraiser is incredible for it's originality in story line; leaving behind the god/satan area of evil and just going straight an other worldly group of creatures that teach that there is no difference between pleasure and pain- there is only sensation. That is not a topic that most horror flicks venture(although that point is not as explored in the movie as in the novella).
Plus, any movie that has a character say,"Jesus wept" just as he is about to be torn apart by hooks (and yes that line was improvised) gets major brownie points in my book.
