The main complaint about these older Superman cartoons is that they are too short to generate enough interest with regard to the otherwise interesting plots and attractive titles, especially since the history and build-up is too long with regard to the actual Superman elements that come later on.
This one is odd in that it really begs "King Tut" but we get "King Tush" instead. By the way, the "u" is short, not long, or it would be even more amusing.
Not much in the line of original action sequences. Animation is very good as usual, but it should have been about a minute or two longer and without the mummy/mother joke which they just couldn't resist, could they? (Sigh.)
4/10.
