Someone said the score for AvPR deserved a bigger, better movie.
SM pointed out that the score lifted elements from bigger, better movies (that being the previous A/P movies).
SM, myself and others then pointed out that this wasn't strictly a bad thing as this is something most composers do, especially of their own work.
SM used Horner as a specific example as he's one of the most well-studied cases.
If you went back and read the whole thread from the last page, you'd see why it was mentioned and that there was no insult intended.
