If you loved Serpico, try Dog Day Afternoon
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Sidney Lumet, and they both carry the bittersweet, raw mood tags, and they sit in Crime / Drama territory. If that's the register that drew you to Serpico, the second film will land in a comparable space — through a different lens.

What Dog Day Afternoon is
Brooklyn bank, summer afternoon, sirens outside. Two men, a botched heist, hostages and cameras. Lumet frames the chaos with a keen eye for social unrest.
