It’s presumptuous to announce in April the worst movie of 2017, so let’s just say “Arsenal” is the leader in the clubhouse. (Spoiler alert: It’s not about the soccer team.) A bunch of B-list actors (Cage, Cusack, Grenier) and some meathead I never heard of (Schaech) perform a Mississippi Delta white trash version of the good brother, bad brother film conceit. Awful dialogue. Bad (Cage, Schaech) and/or indifferent (Cusack, Grenier) acting. Obscenely bloody, stylized violence that seems geared toward 16-year-old gamers. Question: Why would they watch this crappy movie when pretty much any bloodbath video game is better than this?
