Lack of good storyline.

Simple and well acted, it has tension enough to knot the stomach.

The story, direction, characters, and writing/dialogue is akin to taking a tranquilizer shot to the neck, but everything else was so well done.

The thing I enjoyed most about the film is the fact that it doesn't shy away from being a super-sized-cliche;

Castle Sinister (1948) * 1/2 (out of 4)Rather boring mix of horror and WWII melodrama has a man murdered and then it's rumored that his spirit haunts the castle. A government man is sent to investigate and soon the mystery surrounding the murders are revealed.This British film is pretty much unknown to most viewers today and it's easy to see why. The film was obviously shot on a very low- budget and there's really not much going on in the film. Even at just forty-six minutes the film seems to last twice as long and there's just not enough happening to make you interested in it.The biggest problem is certainly the screenplay that starts off with a good murder but from here it's just basically a bunch of people talking. It's really too bad the horror elements weren't played up more because there is a nice atmosphere to the castle and as I said, the opening sequence works nicely.The performances are all rather bland in their own way and there's no question that none of the actors really add any spice to the material. The direction is decent but there's no style to the film and it just has an overall cheap and bland feel to it.

The UK TV channel Talking Pictures TV seem to do a fantastic job in trawling the archives for rare or forgotten movies; CASTLE SINISTER is a case in point. This is a cheap, long-forgotten mystery thriller with a few mild horror aspects, although it's firmly rooted in the post-WW2 era with talk of spies and Nazis on the prowl.The action is set in and around the titular Scottish castle, where military officials have been murdered and a mysterious hooded skeleton is seen prowling the ruins. Is a ghost really responsible, or is human evil at work? Characters investigate, and there are a few twists and turns in the very short (49 minute!) running time.Sadly, CASTLE SINISTER is let down by the extreme cheapness of the production, which manifests itself in below par acting from the no-name cast and direction which is strictly pedestrian. I was chiefly interested in the horror aspects of the plot but these are handled in as much a mundane way as the rest of this lacklustre film.

Castle Sinister is a WWII spy murder things-that-go-bump-in-the- night romp that never really takes itself too seriously. The atmospheric brooding dark Glennye Castle is itself a character of the film and as such it gives the most convincing performance of all concerned. Starring relatively unknown British actors & actresses.The protagonist is a government agent sent up to investigate the rum goings-on at Glennye, where a local agent has been killed and another recently gone missing due to the supernatural appearances of the local spirit. Glennye is supposedly haunted by a hooded, robed spirit of a previous dead lord of Glennye. At the outset this seems a plausible and possibly entertaining murder mystery yarn put in the war context but turns out to be even more far-fetched than a robed hooded spook.The ploy is threadbare and the acting one-dimensional, let alone wooden. Even after the goings-on have been fully explained I still failed to fully grasp the real motivations behind what was going on, and was left very much like I had just watched a b&w version of a Scooby Doo movie - the only thing missing was the bad guy stating 'I would have gotten away with it, if it wasn't for those pesky kids!'Talking Pictures TV - Freeview channel 81, Sky 343
