Yes, I have to agree that this is really not a great film. However, as the previous reviewer has commented, it is worth watching at least once for the 3-D sequences, which were done by the famous Slavko Vorkapitch. The premise is actually a great use of the 3-D medium. Whenever the main character puts on the haunted mask, that is the cue for the audience to put their 3-D glasses (Which were in the form of a "Mystic Mask" when I saw this in it's original theatrical release in 1961!). He then has these wild 3-D dream sequences, which are definitely the ONLY good part of the film. In order for this to work in ANY movie theater the 3-D sequences are in the anaglyph format, which uses the red and green glasses, and does not require a special projection lens or silver screen. The film is otherwise black and white, except for the 3-D sequences, which use the red and green encoding to create monochromatic 3-D. It should be noted, however, that this process does not translate very well to video. The 3-D effect may be significantly reduced or not work well at all, depending upon the monitor, color settings, etc. Probably the laserdisc version of this will have the best 3-D effects.
