Although some call it campy, you can tell that the film makers are fully aware of what they are doing. It is not a parody. Oh no. You might call it an all out celebration of the original comic strip. Everything is overdone - the acting, the colorful sets and costumes, the dialogue - but only within the acceptable parameters allowed in the world of comics. Even the silly jokes are just there for the darn fun of it. And if you had any doubts about my thesis, the final word is the soundtrack, which was written by 80's rock group Queen with the same serious gusto for the subject matter. The blog title is how the theme song begins - "Flash (aahhh!) Savior of the Universe!" - in full operatic chorus. It's just a fun film from start to finish.
serial from 1936 made to science fiction film history. Today all the crazy alien races from other planets featured in the series (Hawkmen, Sharkmen, etc.) would just be considered fantasy material, but at the time it was no crazier than many of the aliens encountered in sci-fi films today. I believe anyone who loves the genre as much as I do would fully appreciate and enjoy the tribute that this 1980 film pays to it, no matter how cheesy.
