Do you have to watch series 5 before series 6, of the tv series the rookie or does it not matter just start watching series 6

While you can start watching Season 6 of "The Rookie" without having seen Season 5, it is generally recommended to watch the previous seasons to fully understand character development, plot arcs, and ongoing storylines. Each season builds upon the previous ones, so starting from Season 1 would give you the best context for the characters' relationships and events. However, if you prefer to dive into Season 6 first, you might still enjoy it, but there might be some references and developments that you won't fully appreciate without the context from the earlier seasons.
