Those of you who love gore and heart-stopping frights won't be that impressed with this film, nor will anyone who chose it purely because of Stephen Gately.
However, if you are looking for a milder scare and a great twist, search no further. Credo is an enjoyable film that lets your imagination do most of the scaring. Those nervous individuals, who don't like to be spooked, will find this a compromise, halfway between "The Exorcist" and "Bob the Builder", which will allow them to say they've seen a horror movie, without spending the next six weeks in rehab.
The acting was surprisingly good, with likeable, hateable and fanciable characters if you are of that age. Myanna Buring was good as the lead actress, with one confusing "wooden" bit of acting that becomes clear later. Nathalie Pownall was extremely good, although why her character had to be a lesbian never became clear and the toilet scene left me non-plussed; however, Nathalie was in no way to blame for the strange directions.
The scenario was a bit of a cliché but the actors managed to create believable characters who were reluctant to enter the derelict college, but desperate enough to put up with it temporarily.
The ending was surprisingly unpredictable. Once you've watched it once, you'll want to watch it again. It gets better the more you watch it.
