“RJ Decker” delivers exactly what you want out of this kind of show. Mysteries that wrap up with the satisfaction of completing a 500-piece puzzle. Characters with depth, charisma, and chemistry. A unique setting that colors it all.

Like its titular character, RJ Decker is a little rough around the edges, but it has a lot of potential.

Once the awkwardness of setting up R.J. Decker‘s puzzle pieces ends, we see the potential for it to be a fun, quirky case-of-the-week detective series that will concentrate on its characters’ stories as much if not more than the weekly case.

ABC’s “RJ Decker,” is a solid crime procedural with an unlikely investigator at its center.

The show has a light, quirk-friendly tone it shares with its Tuesday night procedural partners “Will Trent” and “High Potential,” also on ABC, and if you’re the sort who likes to let a network play straight through prime time, this is a good place to park.

It’s got the same Florida-is-weird vibe as “Bad Monkey” and the short-lived “Maximum Bob.”

The premiere’s mystery feels a touch too gloomy and predictable, but the second episode’s is entertainingly twisty. .... What RJ Decker does not have, however, is a convincing lead.
