Following in the tradition of Halloween teen shockers such as SCREAM, this indie horror flick follows a group of teenagers who overstep the boundaries between the living and the dead. Setting up for an elaborate joke on their girlfriends, Kevin (Jilon Ghai), Freddy (Josh Holt), and Jacob (M. Steven Felty), propose a trip to an abandoned hospital, the third floor of which is supposedly haunted. But things start to get really wrong as they are not exactly alone .....

When you get a movie with a title like "Boo!" about a bunch of twentysomethings who get a kick out of spending a night at a haunted asylum, you can take heed that it'll be screaming of B-Grade.

And that's what this movie is - B-Grade. Representing the first of a string of low-budget horror flicks from the new independent production house Graveyard Filmworks, writer/director Anthony C Ferrante, (a magazine editor by day), gets chosen to take his first shot at filmmaking. Which is probably why you'll get the feeling that he's trying just a wee bit too hard, throwing in everything but the kitchen sink to make you jump out of your skin. "So you want a Halloween scare, huh?" you can almost hear him thinking. "Okay, how about this? And this!? And this!!?" In short, he's made you one heck of a hack and slash movie with plenty of blood and gore like smashed in heads, skinned dogs, dismembered limbs oozing maggots and your usual assortment of apparitions belonging to a little dead girl, a perverted lunatic (M Steven Felty) and a do-good nurse (Dee Wallace-Stone).

But inside of this sticky mess - surprise, surprise - you've actually got a semblance of a storyline. There's a group of friends - Jessie (Trish Coren) and Kevin and Freddy and Marie plus a fifth guy called Emmett who think it's a great idea to hang out in the abandoned Santa Mira hospital, the third floor of which is purportedly haunted by the mental patients who didn't check out of the ward alive. According to the boys' plans, Emmett goes off on his own to set up some scares for the girls at the hospital and we are treated to some chills and thrills involving banging doors, shadows in the corner and the mutation of his poor dog, Duchess. And then the couples come along. One of them, Jessie is psychic. Upon arriving at the hospital, a ghost throws her a set of keys from a third floor window. Those keys, and the ghost, play an important role in the unfolding of the tale.

Meanwhile, Allan, is looking for his sister and her friends, another group of dumb broads who thought that traipsing around an old abandoned hospital was a great idea. Allan approaches Arlo Ray Baines (Dig Wayne), an off-duty police officer, for help. Arlo says no in the beginning, but typical of such movies, follows him to the hospital anyway, and we have seven people, some unaware of each other's presence, creeping around in the dark and derelict hospital. Soon, after a few scares from a malevolent clown, possessed friends, melting faces and dripping limbs, our gang of heroes starts to come apart. They go for each other's throats, or more specifically blow each other up to smithereens, wander off by themselves (as usual), refuse to leave without the other when the door out is just there, etc etc. You know how it goes. And then Jessie, the obvious heroine, solves the mystery of the keys and the ghost.

The acting is generally bad with Allan being, by far, the worst of the lot. Dee Wallace-Stone is of course the best, while the comic relief is Arlo who has lines that are not meant to be funny but you'll find yourself laughing from the sheer stupidity of what he's saying.

This is not something that discerning fans will want to see again. But for kids who want a movie to yell "Boo!" at them, it could be enjoyable.
