Trying to establish itself as an alternative to standard romantic comedies, “Maggie’s Plan” sets ambitious goals, puts in considerable work, but ultimately doesn't quite succeed. It resembles one of Woody Allen’s less inspired efforts—the writing is adequate, but it struggles to generate any real humor. Rebecca Miller wrote and directed the film, basing it on Karen Rinaldi’s original story. Greta Gerwig, a beloved actress known for her quirky roles, is well-suited for the main character. Her likable personality complements Ethan Hawke's performance—he delivers one of his finest portrayals as an anthropology professor (the title might elicit laughter from those who are the intended audience). Julianne Moore also appears as a brilliant but detached Columbia professor. The actors clearly commit to their roles; unfortunately, they’re hampered by a weaker script. This film feels disjointed and inconsistent in its overall feel. It attempts to blend screwball comedy, hipster philosophy, and family drama. There's considerable focus on a young child (Ida Rohatyn), which didn’t resonate with me personally. I believe the scenes involving the child are excessive and unnecessary for the story. Maya Rudolph and Bill Hader have thankless roles; their characters aren’t developed and seem to exist only to deliver a few jokes that don't land particularly well. The plot is thin, and not much truly happens within it. It’s mostly conversations and a series of pleasant events loosely connected to Maggie’s scheme. The film feels forced, and the major ending reveal is predictable even from quite far out. I didn’t dislike this movie, but I'm unsure who would enjoy it. Perhaps it could serve as an acceptable rental for those who appreciate Gerwig or Hawke.
