What we have here is what is pretty much a homemade movie. Someone has a camera and the time and decides to make a film. They try to make a horror movie, good idea, you can do one of those on the cheap and perhaps make something that may not be good, but can be creepy and atmospheric. I have seen very good short films done on the cheap that are quite good and creepy. Unfortunately, this film does what so many other bad homemade films do, they try to make a horror comedy. Why? You can direct someone to scream way easier than delivering a comedic line, comedy requires timing and non actors do not have this timing! So you end up with a film that is made purposely bad that the makers probably gave each other high fives upon completion and somehow this horrible atrocity is released upon an unsuspecting public!
The story, a man mixing a fizzy drink goes to a bed and breakfast in a place that looks like it could not accommodate more than the woman who lives there. She welcomes him, a wrestler, a real estate agent and for some reason they are forced to hang out on the couch. Well, they all go for a walk and encounter a military man and soon murderous mushrooms are attacking due to the man mixing the fizzy drink spilling some of his magic formula.
The film might of worked better had they kept the mushrooms small, but instead they try a horrible larger costume and equally horrible computer effects. They try to be funny, but it does not work because the actors and actress all pretty much suck. The makers of this also would later make Suburban Sasquatch and it is actually an improvement over this. If the filmmaker were immortal I say he would be on track to make a decent film in 10,000 years or so...
So, not good, pretty much like all other horror/comedy home brews. Llamgeddon, Lycan Colony, Feeders 1 and 2 and Suburban Sasquatch all use the formula and all of them fail. Some worse than others, but none of them are enjoyable when watched alone or without Rifftrax and none of them should have been made. You want to make a movie, go for it, but you better have some real actors. If not, do a straight horror film not a horror/comedy!!!
