... Leeanne Walsman's a very good actor, as-and her recent excellent series 'Human Error' attests once again... here, she's not so much a part of each Seven Types of Ambiguity episode, yet when she does appear she makes the most of it, especially that final segment
... Xavier Samuel is actually only several years younger than Walsman, yet he appears onscreen to look much younger than her... and seeing that these two characters in this story are to have been 'lovers' in school, the 'look' of the two of them, and story-timelines of their ages just doesn't work-calculate... maybe as a younger lover of hers, fine... but together in college for several years, just isn't making sense, and it's distracting... in 2017, Walsman's a woman in her late thirties, Samuel his mid-thirties... with a script having them knowing one another for ten years
... all other actors work well in their respective roles... yet with Simon such an important character to the story, it's really difficult disregarding... added to a storyline having long stretches dragging out, and it makes at times for difficult viewing... it's a worthwhile production, yet flawed more than it should have been... Walsman and Samuel did great work.. most all others as well too... another good ABC drama.
