Went to see this yesterday - very good indeed
Has very little to do with the first one (if anything to be honest), and as White Noise wasn't exactly a box office smash I'm a little unsure why they went with trying to link it with the first movie. That said - it stands up very well on its own merits anyway and is well worth a watch if horror's your thing.
(Nathan Fillion is fab in this too, but I;m probably a little biased

- hope to see him do lots more soon!)
