Season 2 has been out on in the UK for several months, and just popped up on Acorn TV. Acorn TV has Roku and AppleTV apps, or you can watch it (Acorn TV) through Amazon. There is a 7-day trial, and Acorn is $5 a month, and worth it for Time Team alone (Time Team is damned awesome). It will make it's way to Netflix, I believe this summer, but if you can't wait, Acorn TV.
Like Season 1, there are 6 episodes in Season 2, each running slightly less than 30 minutes, so you can binge-watch it in an evening. There's also a making-of (don't watch that one first, it has HUGE spoilers).
If you're not familiar with it, it's written and directed by the guy on the right (yes, he's from Pirates of the Caribbean and from the UK version of The Office). It's won a bunch of awards.
It's mainly a buddy movie about middle-aged guys who are into metal detecting, with awesome writing and an awesome secondary cast. There is swearing, but no nudity.
Trailer (Season 1 - the Season 2 trailer has some spoilers):
Simon and Garfunkel are their main antagonists at times:
There is lemonade:
There is (breast) milk:
And there is even a trampoline:
