Wait, so how is the show different from Archer?
Honestly, the similarities are mostly visual. The creator-writer team of Santo Cilauro, Tom Gleisner, and Rob Sitch (the same trio behind The Castle, The Hollowmen, and Utopia), have made Pacific Heat's heroes much, much dumber than those in Archer, which makes the latter feel leagues smarter by association. PH's blue humor is also more reserved (you might come across some sexy situations, but nobody comes close to topping Pam's declaration to masturbate till her fingers bleed), with way fewer obscure pop-culture references in tow.
Ultimately, Pacific Heat is much less about how its characters actually relate to each other; instead, it leans heavily into its police-procedural DNA, with most episodes playing as contained, plot-heavy missions. Cilauro addressed Archer comparisons back in October, noting that he thought his project was more Scooby-Doo meets CSI: Miami. That analogy makes a lot more sense, since Pacific Heat's four main characters appear together in almost every scene, traveling in a pack and functioning a lot like the Mystery Inc. gang. Just, yeah, way, way dumber.
