...and still doing it. I personally don't see why anyone could think that this season is any less funny than the other seasons. In fact, the first 8 seasons started to feel a bit repetitive and dull after a while. By the time the characters had developed from interns to full-fledged doctors, they had gone from frightened "newbies" to confident healers, and their personal lives had developed as well, with them getting married and having children.
But now with a new cast, and new characters to get to know as they (hopefully over a few seasons) develop into respectable doctors in their own right, the creators are able to take new people and give them their own challenges. While the lack of J.D. and Elliot as main characters may seem like a bad thing, the new cast is strong enough that it won't leave you feeling bitter for their absence. Scrubs is as funny now as it has ever been for me, if not more.
I have every episode from the first 8 seasons on DvD, and I've watched them all many times, and I can guarantee you, I'll be doing the same with this season, and every other season they make in the future.
