"It seems like they never say anything bad about actors, they just pump them up"

In this quote, Casey Affleck is expressing his observation that stars are often praised and glorified in the media, with little to no criticism or negative remarks. He suggests that there is a tendency to just concentrate on the favorable elements of actors and their work, instead of acknowledging any flaws or errors. This could be viewed as a kind of "pumping up" or overemphasizing the talents and achievements of stars. Affleck's statement could likewise imply that this consistent appreciation and lack of criticism may not be completely authentic or precise. In general, he is highlighting the capacity for bias and superficiality in the method stars are represented in the media.
