Yes, it was still good, but that first season was GREAT and I would even say perfect, nearly flawless.
They never lost the quality of production, just the writing never recovered from what they were going to do before the writer's strike.
The 2nd season they were supposed to do 6 bonus episodes, kind of "one offs" with people like Kevin Smith writing and directing an episode, each on featuring a new character, and the best 2 were supposed to join the 3rd season.... then the writer's strike killed all of that.
