It’s important to note that Jake Gyllenhaal isn't actually the central figure in this film. The narrative follows a family falling apart, viewed through the eyes of their young son. Ultimately, there isn't much of a plot to speak of, though one certainly could have existed. The father emerges as the most compelling individual within "Wildlife." After losing a job that wasn’t particularly fulfilling to begin with, he manages to hold onto some dignity by rejecting an opportunity to return to that type of work—an offer from the very people who had previously dismissed him. He demonstrates to everyone and himself what it means to put in effort for minimal pay while contributing something positive. That's the storyline that deserved greater attention, rather than focusing on the son’s perspective; he does behave admirably when facing difficulties, but he isn’t particularly engaging as a person. It might have been better if the actor portraying him had possessed more charisma or even resembled his parents, which would have aided in suspension of disbelief. The performances are all quite good, and the film's setting is beautifully rendered; the cinematography is acceptable. The musical score doesn’t stick with you, possibly because the movie’s rhythm feels disjointed, given how little there was to convey.
