This is veritable mishmash of indie movie tropes put together in one cutesy little boring film. Think "dull" Greta Gerwig or Noah Baumbach and you would be close to how this movie feels and plays out. It pretends to be do a different take on the meandering life of its very confused protagonist (which means her motivations are usually a total mystery) by using some very done to death tropes like that "children are so annoying at a family party" scene or an overlong "cutesy no touch romantic scene" or using a onscreen narrative device in the most annoying and inconsistent fashion. The filmmaker here is going for whimsical smartness but ending up as ho hum sleep inducing ride which just recycles what has been done before in a very very dull way. Please avoid.
