So boring, this film
22 October 2006 | by (Beverley Hills, England) – See all my reviews

This is my third Reginald Le Borg film and, like the other two, it's a largely dull and boring affair with very little to recommend it for. The first Le Borg film I saw was the 1957 chiller 'Voodoo Island', which managed to be completely lacklustre in spite of the fact that it starred horror icon Boris Karloff and featured a decent plot. My next taste was the 1963 Vincent Price film 'Diary of a Madman', which again managed to squander a big star and a decent plot line. Which brings me to Psycho Sisters - a film with an interesting title, but without a big name star or an interesting plot and, rather unsurprisingly, the director does nothing to elevate the film above bottom of the barrel cult cinema. The plot focuses on a woman distraught after the death of her husband. Her younger sister consoles her and its not long before her sinister motives come to light. I went into this expecting a merely decent slice of seventies horror, but got nothing like. The plot is soaked in tedium and it seems to take forever for anything to happen as most of it is taken up with dull lines of dialogue. , meaning that by the time the plot reveals itself; any audience member is likely to be thoroughly bored with the film. The production values are cheap and tacky, and the acting reflects this as none of the stars are able to deliver meaningful performances. Overall, this film really isn't worth bothering with and I'd recommend not tracking it down.
