The Superman story is very bad, but what can you expcet from single issues stories from the 70's, for the most part. The story is ok if you like father & garndson off to rescue grandfather, but other than that it is boring.
The Private Life of Clark Kent is a laughter. Change Clarks' image Morgan Edge says. Boy does that go wrong. If I could rate the stories seprately, I'd give this one four stars.
