I can barely believe I watched this to the end - this is, without much doubt, the worst film I think I've ever seen, and I've seen the Dungeons and Dragons films. The clunky, heavy handed plotting, the glaring genre signposting, the rabid cliches, generally awful acting, the painfully ridiculous wobbly fight scenes, the equally wobbly demon fingers, the drudgery of the action, and the condensed and, frankly, token ending climactic (maybe climatic would be a more appropriate term, used in relation to the weather in this film's case - it did have some nice weather shots, which felt more urgent than the plot ...) scene punch this film into the minus score zone.
In fairness, there were some nice scenery shots, and there is, perhaps, something to be said for the villiage architecture aiming at something more generally 'historic' (at least they tried). Keeping one eye on a pretty hunky Hadrian Howard did keep me awake at least, even if he had some dreadful lines (admittedly getting some stiff competition from pretty much every other character in that department - and the accents were awful). As others have rightly said, if this was billed as a comedy it might have worked, with a bit of additional effort - it did have its 'you've got to be kidding me' moments - but the wink to the camera just doesn't come.
That is and hour and a half of my life I clearly won't be getting back.
