I don't think anyone has said it would be better, just perhaps different. And different can be good.
As for serialised vs episodic, perhaps the DSN route of semi-serialised is the best of both worlds.
On the continent of wild endeavour in the mountains of solace and solitude there stood the citadel of the time lords, the oldest and most mighty race in the universe looking down on the galaxies below sworn never to interfere only to watch.
