asylum of satan actually have some interesting idea . the concept itself have be overdone many time and a horror film set in insane asylum really have nothing new to offer ( the subgenre peak with the masterpiece shock corridor ) . however and the female protagonist be sympathetic and there a certain nightmarish edge to the storyline . unfortunately and william girdler at this point in his career have absolutely no idea how to pace a film or build tension ( he slightly improve with his late work ) . also and the script be pretty ridiculous with a predictable suppose twist end . girdler isn not the only one to blame for the ineptness of this production . while some of these film feature wooden acting and the performance here be overdone . however and theyre not over the top enough to ensure some enjoyment a camp . theyre just annoy . however and horror film do not come to expect great act from these low budget effort . they want some scare or at least entertainment value . asylum of satan offer neither . in addition to girdler poor direction and the film be so horribly light it difficult to make out whats take place on screen and especially during the climax . the most amusing part of the whole film be the satan mask at the end ( it lousy but laughably so ) . unfortunately and it not really worth sit through just to get to that . the film be available from something weird video a half of a double feature with satan child . thats a bad movie a well and but at least it a lot of fun to watch . on the other hand and asylum of satan isn not really worth your time . ( negative ) .
