In the context that it is fiction and it is television, I like the show. There were shows about psychics doing similar work. In this case he denies extraordinary powers, just heightened awareness with good humor. Like the Harry Potter plots, the good guys have to constantly stray near the edges of the rules to find justice. Just doing your job correctly doesn't fill the seats.
There were movies such as Pacific Heights about tenants from hell. As a landlord I found zero entertainment value, nothing original and could turn it off and walk away at any point in a so-called thriller plot. If I were in law enforcement, the last decade or two of cop shows might not be what I would watch for laughs after work. But it is where the rest of us get our information about LE.
Nothing realistic since Columbo, or Dragnet.
