My first reaction to The Eye 2 is simply "YES." Hell yes, even, because this is exactly what I want to out my ghost movies. This is the kind of supernatural activity I want to see, and this is the kind of story that I want to see play out. Also, The Eye 2 is not a true sequel to The Eye - a true sequel being one that continues the original story in some way. The only thing these two really have in common is the name and a chick who can see ghosts. She has "the eye," or something I guess. Not that I cared too much about that while watching the movie because I think The Eye 2 is certainly good enough to stand on its own.
I didn't have too much hope for The Eye 2 when I first started watching it because I'd never heard it mentioned anywhere else before, but it ended up really surprising me. The lead actress is wonderful and carries the film exceptionally well, the direction is perfect, and it scared me a couple times. Big win for me! Watch The Eye 2 for the good ghostly stuff, but definitely stay for the really nice ending.
