I've always had a (somewhat morbid) fascination with Chernobyl and the #86 Meltdown and the repercussion and such. When I saw this advertised, I wanted to see it due to the name, but then the trailer looked great too so I went and saw it with my sister. The film was good - scary, but not ridiculously scary (a la #8 and #7 ) so I liked it.
My only real criticism about this film is the ******** excuse for a 'twist' they put in the end. It was predictable, it was poorly executed, and it was overall pathetic. I won't spoil it for anyone that hasn't seen it but it was just unnecessary - the twist wasn't even involved until the last 4 minutes of the film.
