This is a good film, and it's still a good film upon seeing it again, but some parts just rub me the wrong way, one of them being Kirsty's first on-screen appearance. She seems agitated, and is acting, in my opinion, oddly, yet no reason for this is given (unless it's just the stress of moving to London, which is possible). That's another issue I had, though - while this movie is supposed to take place in London, most of the characters seem to have American accents. I realize that this was a decision by someone who believed that it'd help with American viewership, but still, it sort of took me out of the immersive experience I'd have preferred.
Lastly, the homeless man/demon is following Kirsty before there's any real reason for him to do so. Again, never expanded on. Still, the movie is solid. Cenobites are fantastic, Kirsty is a decent (and easy on the eyes) character, and Frank/Julie are quite the threatening pair. And of course the special effects are extremely solid for the most part. Overall, it's a good film with a flaw or two. Certainly worth the watch if you've not seen it before. Great 80's horror.
