I can't quite understand these alleged Bergman "fans" who say that this film is somehow lacking. Whereas "The Serpent's Egg" is not on par with say, "Fanny and Alexander" or even "Scenes from a Marriage," and even though it is, admittedly, not "Bergmanian" in the sense that the director's strength lies in acute insight into the emotional complexities of his characters, it is NOT, in any way whatever, an inferior film. Here we find Bergman writing and directing a film that steps briefly away from his norm. The fact that this film is better than, for comparison, anything from Polanski (who's "element" is the long-winded suspense film) makes it worth much regard. In fact, I am moved to say that "The Serpent's Egg" is a display of writing/directorial versatility that remains unsurpassed to this day.

This being said, no film should really be rated in terms of previous works of its own writer/director. It should be rated in comparison only to other films. Bergman is a superior director and one of the most talented writers at that. Whereas Bergman himself always strove to be better than Bergman, we should be fair for a second and admit that he is almost always better than anyone else.
