Does the Harry Potter movie series distort J.K. Rowling's own version of Harry Potter?

Like the rumors of Hermione and Ron..or even how Harry Potter looks like...do you guys think Rowling just moved with the media's perception of "Harry Potter"? I remembered that when the first book came out, "The Sorceror's Stone," the cover had a boy on a broom. Then, when the movie came out, all her book covers seem to resemble Daniel Radcliffe instead of the first boy on the first book cover...I don't know...what if Harry Potter wasn't made into a movie? Do you think we'll still feel the same about these characters?
