Taken for what it is, a 1977 TV movie, "Force of Evil" is above average entertainment. I'm not going to kid you though, believability is not one of it's strong points. Lloyd Bridges plays a doctor, and while Lloyd Bridges may not be able to tell when someone is dead, a doctor definitely should. The entire last half of the film pivots on this point, and drags everything down a notch. The acting is scattered, although William Watson is memorable as the villain "Teddy Jakes". There are definitely some scenes, such as the mom and daughter discussions on the houseboat, that I could have lived without. I actually rate this less than IMDBs 7.7. To me it's a 6.0 at best, because it seriously challenges believability. - MERK
