Those that called this movie boring...
missed the mark I believe. I saw this movie when I was about 12 and found it to be very eerie. The fact that it was confusing intrigued me. The ending left me wondering. Every time I would watch it, I would come up with a different explanation. I was never sure which twin was alive at the end and why.
THAT type of controversy itself makes it a GREAT movie. I'm glad to see it on so I can record it. It's definitely hard to find.
