Sure, but Lady Macbeth's storyline was always directly involved in the main plot. Many of Claire's scenes just came off as padding.
Although, I guess the definition of "padding" is up to taste for show's that are highly character-focused. I just didn't think Claire's were very interesting.
To be clear, I'm not talking about her enviro-group. That tied in several times to the main plot. I mean theyelling lady, taking Russo's kids, the homeless origami dude, hell even Adam was a bit of a waste of time to an extent.
I agree Adam was a really lame plot point. It really went nowhere, and only served to remove Claire from Frank's storyline late in the season to add dramatic tension. It was a weak narrative. But I think the other elements are important for her character. They weren't "plot" scenes, so much as "reaction" scenes for her character imo. They show her grappling with hints of regret and indecisiveness about her direction in life, similar to how Lady Macbeth has a slow emotional breakdown. Adam was crap though. Fuck Adam. Lol.
