In a word, boring. Requiem for Krypton is a behind the scenes look at Superman Returns, that at times seems like a carpenters instruction manual.
The lack of post-production material really lets this down, and it doesn't have the same insightful and entertaining material that you could find in Episode 1: The Beginning, or Empire of Dreams. It starts off pretty well, and there are a few great moments, but that's all they are, moments.
Too much time is spent on certain aspects of the production, such as set-building, and not enough is spent on what people most like to see in behind-the-scenes features - the people. while there are a few nice moments with the cast and crew, for the most part, their reactions to the camera seem stale and the makers of the documentary seem content to just go back to set-design over and over.
Even those who like the "technical" style featurettes found in DVD's will find this disappointing, with many interesting subjects getting brief mentions and nothing more and as I said at the beginning, the lack of post-production footage is a real letdown.
Overall, the doc is alright, but too many boring and tedious moments overshadow the interesting and insightful parts, and it feels like the stuff that didn't make it into the final cut was a real loss and should have featured, much like the deleted scenes in the actual Superman movie itself.
