Most channels have an identity based on the series they air. For example, CBS is the “crime-of-the-week” procedural channel for Boomers. Prime has become the place for not-too-challenging “beach read” shows like Reacher, Bosch, Goliath, and Jack Ryan. Cross is the latest addition to that type of programming. If this kind of show is your jam, it’ll unremarkably scratch the itch. The central investigation is interesting enough, but there is a second mystery that is needlessly tacked on to the end, resulting in a final episode that is all filler. However, the relationship between partners Alex (Aldis Hodge) and John (Isaiah Mustafa) keeps it watchable.
