4.5/10 would be just below average in my ratings too.
I recently saw Shutter an american remake of a Thai movie that I am sure was better but this one was pretty good in my book. The story is a bit cheesy, Spirit Photos where you can see the ghosts only in photos (or sometimes reflections) but it gets better as it unfolds and the I was quite moved in the end. The final image was one of the most haunting I have seen.
6/10 (Just above average, enjoyable)
