This movie falls apart on several fronts.
Number one. It poses the question of "How did George Reeves get those bruises?" Good enough question, I suppose, and the movie makes a point of asking it more than once. Problem is, that when the film ends, no one has bothered to explain the bruises! Why do filmmakers insist on making points about things they're unwilling to explain? Because they have no respect for the audience, that's why.
Number two. It insists on telling us two stories; the quest for answers about the death of George Reeves along with the relationship of Adrien Brody's character with his son. Now that wouldn't be too bad except that the movie is two hours long and this father/son thing just goes on and on and on. Yeah, the papers say Superman shot himself. Yeah, he's no longer with us. Yeah, life is tough sometimes. Make the point and go on; don't keep dragging it out.
By the way, I am 56 and watched Superman religiously as a child. Yes, I was shocked when the news came out, but I sure didn't go into a deep depression. And I didn't know anyone who did. Back in those days, kids didn't have only one adult hero to look up to, they had a plethora of them. There were Roy Rogers, Gene Autry, The Lone Ranger, The Cisco Kid, Wild Bill Hickock, Flash Gordon, Robin Hood, Hopalong Cassidy, Sky King, Sgt. Preston of the Yukon, Annie Oakley, Jungle Jim, Ramar of the Jungle and many others. So losing a hero was bad, but not so devastating that a person could barely continue to function. Not to say that couldn't happen. I suppose it could, but I never heard of or saw it.
The second problem with this movie is that it lacks action. You know, in most good film noirs, the hero gets beaten up at least once. The hero in this movie gets whooped, too, but you have to wait over an hour before anything happens. The movie is just repetitions of "flashbacks on George Reeves," "dealing with my son," "flashbacks," "dealing," etc., etc., etc.
The third problem is that Ben Afflack does not play Superman very well. Now, I will admit that he does a good acting job as George Reeves--he actually seems to be playing someone other than himself. But as Clark Kent or Superman his performance is lacking. In fact, he looks to me to be too self-conscious that he is wearing the Superman costume. He looks as though he's thinking, "What in the world am I doing dressed up like this?" Also, I don't know who dressed him as Clark Kent, but they did a horrific job. The suit looks too big, the hat looks too big, and that makes him look physically small.
And, then, when he is doing his running leap as Superman his facial features are those of grimacing pain. Why didn't someone have Mr. Affleck study how Mr. Reeves performed that stunt and then try to duplicate it? Who knows.
Anyway, did you know that Superman was the first TV showed filmed in color? The producers had the foresight to predict that color TV would one day be the viewing standard and so thought and acted ahead of the crowd.
Your better bet: Superman DVD Sets Volume one and two.
