Memory (2023) review

Social worker (and recovering alcoholic) Sylvia (Jessica Chastain), who lives with her young daughter Anna (Brooke Timber), attends her high school reunion but is followed home by a man named Saul (Peter Sarsgaard) who, as it turns out, has dementia; later, Saul's niece Sara (Elsie Fisher) asks Sylvia to take care of him ... but the issue is that Sylvia's convinced he and a buddy used to sexually abuse her when she was a child.  As the title suggests, it's about matters that are either (a.) forgotten entirely (due to disease) or (b.) misremembered, yet the scenario itself is a little too conveniently assembled, scenes feel half-written (or not thought all the way through) and then it stalls out dramatically ... until Jessica Harper's grandmother pops in to act shrill and deny past events (which is what families sometimes do to "maintain order").  Since Chastain's character apparently has a fear of men (she even puts in a request for a female to fix her refrigerator), the "romance" that develops between her and Saul is worrisome: are there no able-minded fellows in the city left for her to bond with?
