In its fourth season, “Bosch” remains as good and solid as its namesake hero. The creation of author Michael Connelly, good ol’ Det. Hieronymus “Harry” Bosch (Titus Welliver) is a no-excuses cop who is haunted by his past, but you wouldn’t know it because he’s also incredibly businesslike. He’s not crippled by his obsessions nor addictions, he’s not a quirky savant with exceptional detecting skills, and he’s not in any way an obnoxious attention seeker.
Instead, his appeal is that he does his job without fanfare and as honestly and implacably as possible, while occasionally overextending himself. And so too does “Bosch” the series. It’s why it was Amazon’s top-watched original series for several years until “Sneaky Pete” sneaked in: “Bosch” is so reliable in how pure and straightforward it is that a series-altering event in the first half of the season is actually shocking when it happens. More on this later, but we promise no spoilers.
