The many (too many?) plot lines in Slings & Arrows Season 2

As M observes, part of the fun of "Slings & Arrows" Season 2 is that we see multiple productions taking shape during the festival season: Macbeth (Jeffrey's show), R&J (the crazy European-influenced director), and now in episode 4 the original Canadian production with the temperamental playwright in charge. We learn about different aspects of theater and the life of the theater from each production - really funny watching the actors go through their exercises, in R&J reversing genders because of some crackpot semiotic academic theory the director barely articulates and in the original production they struggle through a staged reading as the director keeps throwing away his own script (he's hyper self-critical). Meanwhile, Jeffrey stands up to the vision of Oliver and determines come what may the Macbeth has to be his own production and not Oliver's - great, because what makes this duo work is or should be that they have very different visions of the play and of theater, and S&A loses sight of this too often. Jeffrery fires Henry/Macbeth, which will obviously lead to tensions, as they guy's a brooding egotist. Two other (too many?) plot elements as well, as Ellen is undergoing an audit of taxes (not sure what this brings to show) and engages in a sexual fling with her brother-in-law (I wish she hadn't, we were all beginning to like her), and Richard is going off the deep end with this crazy but funny ad campaign - perhaps this is being pushed too far toward the ludicrous. He has to stand up to them, as he did in Season 1 and as Jeffrey is doing in Season 2.
