stewart moss star a a scientist who be on a working trip with his wife and and one get the feeling that he be pick for this role for his ability to roll his eye back in his head . imagine the audition for this . can you . no and that not quite it and thank you and next . anyway and he bitten by a bat and and then and he either change into some kind of bat creature and kill people or . he not . for no one else see his strange transformation and but he himself seem to think that he change because his wed ring pop off when his hand turn into claw and etc . to it credit the movie do kind of hold back on whether he just nut or whether he actually transform into something until almost the very end . this have some good location and sort of a decent atmosphere at time but unfortunately none of that can make up for the somewhat lame story and the wonderfully bad act . kind of fun in a so bad it good way and but lean more towards just plain bad . 4 out of 10 .
