One thing I always liked about the pilot is the fluidity and kinetics of it. It's a standard I don't think the main show ever really matched. When I read the comics, I think of Batman as being able to move so quickly that it seems plausible somehow that he could dodge a bullet. The pilot communicated that idea pretty well with a pretty heavy 1940's/noir/crime atmosphere. BTAS is an awesome show and I'll never say otherwise but I felt like the animation wasn't always quite up to par with the material.
