The Mythoscope makes a virtue of nescesity , and the effect works well. You might well think it was an old Universal horror flick, just as 'Call of Cthulhu' looks just like something FW Murnau might have done.
Of course, the smaller budget is at the root, but I must say, I love Mythoscope. I also love the props and tchochkes they purvey.
The film is a departure from the story, but on film, its a better story. I love the 2/3 scale Curtis Jenny in the climax. The bonus reels explain some of the magic, but are almost more fun than the actual movie.
I have all the films the HPLHS offers, and enjoy them greatly. The audio "Dark Adventure Radio Theater" is authentic 30's spoken drama
