Just re-watched it a few weeks back and yeah, it's really not that amazing. Really all of breaking bad is kind of overrated, as good as it actually is.
What happens in it?
I felt the suitcase was a pretty normal episode of Mad Men. I didn't know people were losing their shit over it until after. The Wheel though, that episode has a godly moment that I am fairly certain is one of my favourite moments in tv history and Man Men will likely never top it.
