Like some TV dramas in recent years (Game of Thrones comes to mind), they went for the big bang on the second to last episode and let the season finale be the denouement and the stage-setter for the next season. Which is pretty much fine with me, but yeah this episode wasn't anything spectacular. The bingo hall scene in particular may have seemed good on paper but didn't work in execution imo.

Still an incredible first season, can't wait for the next. Count me among the initial doubters who became believers.
