This is an exerpt from a review of the Transformers.

Colors are bright, rich, and deep, perhaps a tad too bright, rich, and deep for real life, and a touch glassy, too, but appropriate for a cartoonish movie like "Transformers." Definition is, as we might expect, near flawless, the crispness of the delineation serving to point up every detail in the mechanical creatures.

I read the movie was intentionally made this way to give it that cartoonish feel as the reviewer pointed out.
I believe as you get the opportunity to see more movies in HD you will truly see a difference in most films, some huge some minor, but I have yet to see one that was worse in HD than in SD.
