wow, the trailer makes the movie look even worse than it actually is. usually trailers have the opposite effect. no wonder this sunk like a stone at the box office. I don't think Doc could be brought to the screen properly now, it's definitely a product of it's time. I am surprised it was never made into a serial back in the 30s or 40s... can you imagine what Republic might have done with the property?
I'd say enjoy the trailer, but it takes the worst of the movie and shows them to you. I wonder how ten year old me would have reacted to the film back then?
