I saw this (all fifteen chapters) as a young kid, and along with my friends I was mesmerized. Kids didn't notice that the final scenes of each chapter didn't exactly match with the beginning of the next week's episode, but what the hell. Batman and Robin were able to get out of those jams, and that was what really mattered. Special effects were par for the time, especially considering they were on a low budget.
An earlier comment criticized that the film referred to Japanese as "slant-eyed". There was no political correctness in society at that point. America was at war, and even newspapers used rougher descriptions when making reference to Germans and Japanese. The film also mentions how wise it was to round up and interne all people of Japanese extraction. This was 1943, and the serial was reflective of the public mood of the moment. No apologies should be necessary.
