Below average, but has its moments
For me the movie went down the drain pretty fast after and due to thelack of scriptwriting talents few obviously infected convicts wereforced to the canteen, so the hell surely broke loose. Nevertheless theidea of zombie epidemic in a high-security prison was still interestingto follow.
Apart from the script, the camera, most of the acting and especiallysound work were killing the concept frame by frame. Ten repetitions ofguts being pulled out of the bodies... Constant green toning of thepicture, why?.. Gunshots poorly synchronized with video.. I don't knowwhat was making me follow - I guess it was the concept itself again.
But somewhere in middle of this bad taste pride parade I was broughtback to life by one totally brilliant scene. It was a shotgun slaughterwith classic piano concert in the back (something from Tchaikovsky's"Seasons", I guess). It was so perfect match of time, picture andsound, although this trick is not a novelty (check e.g. The Silence ofthe Lambs). So while making your mind please take into account that Iadded one extra star for Thaikovsky.
