Catching up on "Sirens" - TV Series

I saw the ads for "Sirens" a TV series partially created by Dennis Leary, and it looked like a modern take on "Police Squad" or some other "Airplane-like" slapstick comedy.

I was surprised that the series is actually a little deeper.  Not changing into a drama, or a '60's remake of "Emergency", but a comedy based upon paramedics in Chicago.  The characters are stronger than I would have expected from the ads, and the writing is pretty good.
