All these negative comments, i was at the premier last night and was truly impressed. I wasn't expecting much, but was genuinely scared in parts, which has not happened to me in a long time with a horror. Paddy did a great job of mixing the typical slasher genre with the supernatural feel of an Asian horror flick, something that will be copied in the near future. The sound was terrific, perfectly complementing those darker scenes, and although the movie is called shrooms, it does not linger over that fact. There is very little "shrooms " in the movie, they are more of a door for the creative side of the director to run free. In finishing, this is not the best horror movie you have ever or will ever see, but it is definitely worth a watch.
