Great horror flick! This is what suspension of disbelief is for! A rocking, gory, loud, sexy, terrifying ride! A well acted horror-thriller and ultimately that's what makes the movie. Formulaic characters (mad scientist, hot assistant, hotter crazy chick, sociopathic bad guy, brilliant inmate who can't cope in society, etc), a well worn setting (the inmates are the sane ones! science has run amuck! No one notices!) and some pretty tough to swallow plot devices/coincidences (I'll just 'pretend' to be crazy and get admitted to the crazy house where I'll have free rein and no one will notice I'm really lucid if I keep folding my arms and ducking my head) - but the whole is better than the sum of the parts and somehow this one works well, really well. I enjoyed every minute the insanity at the insanitarium!
