The second I saw you lazy, fast pace, I immediately thought of Romita Jr. His work in Action Comics was notoriously horrendous there.
The lazy, rushed feel is widespread and it's due to industry pressures -- like always. Instead of polished artwork, some of the illustrations look like hastily done sketches which are marketed as being "modern." Lazy, heavily shaded coloring is "gritty." Dichromatic coloring is "cleverly stylized." Like Superman Red and Blue. The fact that these styles are all cheaper and faster to churn out is no coincidence.
