Really, my summary line sez it all.
This film does a valiant, necessary job: In its scant 80ish minutes, it gives a passable broad view of the evolution of the comic medium in the U.S.
Take it from me, if you grew up with comics in the 60s thru the 80s, this film covers an impressive array of the essential bases. One of the highlights, to me, is basking in Will Eisner's beautiful visionary mind.
And the other minds you see are lovely variations on that central theme.
Wonderful, wonderful, wonderful! Lovely production values, highlighting--just like comics! Fancy that!--the power of wild, middling production values coupled with untrammeled creativity to speak simple, direct truths that touch your heart and free your mind.
Check it out.
