ALL the episodes were good, in retrospect. I've been watching the DVD encodes, and even in episode 1, we see Nagasumi acting GAR, we see the personalities of the various characters showing through in amusing ways, the music isn't bad, there's decent animation, etc.
But for some reason, the first time through, it felt slow. Probably because I didn't know the characters, and thus didn't appreciate all the (well done) character based humor.
So I understand your viewpoint quite well, but I also sympathize strongly with first-time watchers.
