We love it. There's a single crime/mystery each season, and the overarching story of the murder of Bosch's mother (kind of like Monk in that respect). Bosch is your standard troubled cop who doesn't play by the rules, but the writing is strong enough that I don't mind the tropes.
Though I must say I cringe every time they remind us that his full name is, you guessed it, Hieronymus Bosch.
