Swashbuckling. Juvenile. Ancient. Terrible.
I'm sorry, but I just can't find any redeeming qualities in this story. The writing is archaic, like that of Wells, and there is no particular plot. The ending is no ending at all. I don't even see how this can be classified as science fiction.
If this were a movie, and it was in color, and had real sound, then... children would probably like it. If you've reached any sort of maturity, not so much.
Quite an interesting premise to this story, but it degrades into silly science and a juvenile ending. You could find better things to do with your time than read this story.
