Actually, I think the first two series are one of the better portrayals of being at the bottom of the hospital pile. Yeah, now he's an Attending they've kinda given up on a lot of the medicine and the over-written backstories are making it unwatchable unless you've seen every bloody minute of it but I've rewatched the early ones on E4 in the last few weeks (After first seeing them in 2002) and they're still very very good.
Bodies was good (Again, particularly the first series) but it suffered from the same thing that a lot of "Realistic" medical shows do, that it saw negativity and darkness as a virtue. Yes, things go horribly wrong, you hate a lot of other staff, you have constant inter-department conflicts and the management will make you want to die but Scrubs is the only thing that seemed to get across that beneath all the jaded, cynical crap the health service is still run by people who are passionate about their work and basically enjoy themselves. I mean, I'm on the worst placement I've ever had at the moment and not enjoying things at all day-to-day but if I didn't still think this was the best job in the world for me, I'd quit tomorrow.
