More specifically, the main things I liked were:
- Colette. It's being called her best performance and I agree (and always liked her in other stuff as well). An intense role, full range of extreme emotions on display, yet no "acting" visible. Horror film performances don't get much better. You'll probably think this heresy but I think it holds up next to Isabelle Adjani's performance in "Possession".
- Charlie. The actress was perfect in both performance and appearance and I just really liked the film's approach to the character. They struck the perfect balance- she was creepy and weird but not in a typically OTT horror movie way. And w/ the possible exception of the whole bird beheading sequence, the film never really hits us over the head w/ fact that she's *evil* until the end
- the post Byrne burning sequence. Unnecessary reincarnation speech aside, I find the sequence to be brilliantly constructed and truly unsettling. I bought the film on Blu Ray and watched this sequence a couple of times standing in front of a big screen HD TV and soaking in all the creepy details. Might seem silly but possibly my single favorite moment in the film was when the son hides in the attic and we hear Colette pounding on the door and then it cuts to her on the ceiling banging her head against it. Such a striking image and a rare case of a film managing to be genuinely unsettling and also darkly humorous at the same time
