Disappointing sequel, considering Naomi Watts and the director of the original Japanese Ring were on board. I enjoyed the first movie, but just felt this one strayed too far away from the original concept. Most of the cast are woefully underused (the film was either heavily edited, or just poorly constructed), there are many plot holes and scenes that need explanation but receive none, and the heavy use of water imagery has already been done in the original Dark Water film.
On the good side, the film was well shot, although some CGI was a little ropey.
Worth seeing? Just. A few minor scares, but nothing more.
