Agree with this 100%. Sometimes film-makers do improve on the source material.
Another example of this was the 2002 Spider-Man film, directed by Sam Raimi. I thought it was great that they explained Spider-man's "webbing" as being produced by SM himself, organically (like an actual spider produces it's web) instead of artificially, like it was always described in the comics - i.e., Peter Parker/Spider-man made this in a lab?! - somewhat ridiculous explanation....In fact, IIRC they had an interview with someone @ Marvel when the SM film came out, and they said something like "I wish we had thought of that idea" (or something along those lines).
