This movie is very interesting and captures your attention with its excellent premise. Something in various parts of the world that people see is causing them to kill themselves an/or others. It is well played by Sandra Bullock and John Malkovich and others and quite believable. I give this 7 stars only because the "creepsters" are never actually seen by the viewer and ARE NEVER explained either. This is a typical Stephen King or J.J. Abrams thing in their movies. For anyone who wants a completeness about their movie(s) it is extremely annoying - even more so the more unlikely the story is.
