Much of Mike Mills’ “Thumbsucker” treads fairly standard young adult coming of age territory. Lou Pucci’s Justin Cobb, the protagonist whose titular habit serves an effective metaphor for his juvenility, must undergo familiar trials that provide him confidence and self-worth. He has to learn public speaking skills and romantic graces with a decidedly modern twist – Justin has just added medication for his recently diagnosed ADHD that totally transforms his personality.
But there’s something more to “Thumbsucker” that makes it my “F.I.L.M. of the Week.” Mills, working from a novel by Walter Kirn, does not stop the coming of age with Justin. As it turns out, his emotionally stilted parents have plenty of growing up to do in their own right. The film is just as much about their own slow maturation process as their son’s.
Vincent D’Onofrio’s Mike insists that Justin refer to his parents by their first names since the terms “mom and dad” make him feel old. He serves as the manager of a large sporting goods store while still nursing bitterness and resentment over a knee injury that thwarted his football career. His family serves as a daily reminder of what his life is not.
Meanwhile, his wife, Tilda Swinton’s Audrey, handles all the love and affection for their two kids. She’s genuinely curious and attuned to Justin’s issues. But Audrey cannot shake a girlish fascination with a soap opera actor Matt Schramm. The infatuation reaches levels that embarrass her children; they do not think she would literally cheat on their father, though she is not exactly quick to dismiss the possibility of her fantasy.
“Thumbsucker” shows everyone fumbling through this thing called life together in their own way, and that even includes Justin’s zany, hypnosis obsessed dentist Perry Lyman (played by none other than Keanu Reeves). With over a decade of distance since release, it feels very reflective of a mid-2000s suburban malaise that already feels like a time capsule. Mills is earnest in his explorations of what causes people’s unshakeable, throbbing sensation of vague discontent with their current situation. The sincerity goes a long way in making these unsatisfied characters ones that are worth spending time with to probe their pain.
