For me that's Scrubs. As someone who is majoring in the medical field, it's the only accurate medical show. And it's better than Greys anatomy and House MD. Plus it has a dark sense of humor which I love. This is still the funniest line from the show.
Ah Scrubs is SO good!! For me, I think The Office (US) is extremely under-rated. It might be huge in America but in the UK, barely anyone has watched it or only watched the first series then thought it was crap :( And that just kills me!!
Also, Summer Heights High is most definitely under-rated and is my favourite ever
I wouldn't really call scrubs underrated, but ok. I'll have to go with darkwing duck, freakazoid, life (fuck you 2008 writers guild), an idiot abroad and/or the Ricky gerveis show, Jane the virgin (don't judge me 😛) and vice principlals... I'm also missing 1 or 2, but whatever
