Superman

This is one good serial! There is a lot of action and decent SFX and fairly good (if now stereotypical) characterization.

Kirk Alyn is great as Superman and Clark Kent...a performance that really wasn't surpassed in any media until Christopher Reeve's triumph in 1978. Lois and Jimmy are suitably doltish...though even Lois was a bit more intelligent in the comics than in this serial.

I've been told that the producers had some remorse at the cheapness of the effects (i.e., using animation for Superman flying), but I really don't think it comes off as shoddy...in fact I think it comes off fairly well, or at least better than using a derivative of Republic's effects for making Captain Marvel fly seven years earlier.

Superman is supposedly the most popular chapterplay in history. I don't know about that, but it is very enjoyable and an excellent example of the genre of the movie serial.
