They rushed out 65 episodes, and it is impossible to shit out that many episodes in that short a time period and to maintain quality. Everyone remembers the 10/10 eps, but not the ones where the animation is an ugly mess.
On the bright side, DCAU is one of the few American animated productions where they saved the original 35mm film reels, meaning they could rescan them in HD. Pretty much every other show from my childhood is stuck in some horrendous SD DVD quality with a horrible transfer. That even includes shows like The Simpsons.
The reason? They thought they didn't need these reels anymore, so they transferred the shows to Video Tape masters and destroyed the originals.
