I've seen all of the episodes. The first two are definitely the best, but all six have their moments. It's really cool to see all of them because each episode is a year apart and you have to piece together what changed. The brother who still lives with the parents has a different job every time.
And yeah, I've heard of that series. I think I watched like, one episode but it never entertained me a lot. The comedy shows we have in Australia surely are fun once you get into them.
