Okay - if you've read any books in the "Doc Savage" series you'll recognize the personalities of Captain Future's team - and the members have the same dynamic to them, even though the species are different.
That being said, it's hard not to like them. This book touched me on many levels, and remains one I like despite how utterly corny it seems nowadays.

The main persona tracking use of this book is to examine how the interrelationships of the team touch your feelings as you age. Do you view them with a hope to have friends as nice as these are? Or do you view them with nostalgia as "dated"?
