I don't watch it with a critical eye, but the contrast between the Jeremy in the first part of the series and the latter part did not end it on a positive note for me.
I've met more than my fair share of industrial sales reps, and many are nice guys, but if I was one who took part in that tractor charade, I'd be miffed at least.
I'd welcome seeing more of Harriet, or others telling Jeremy that's he's full of it sometimes. Even Charlie is being painted as more neutered compared to before.
