Origins. This is not a brag; normally, as a reviewer, I’d try to conceal my ignorance as best as possible. Ideally, I’d take time to catch up on episodes of the original before attempting to discuss the prequel in order to place the series in its proper context.

The latest spinoff of the long-running CBS procedural is an occasionally awkward introduction to Mark Harmon's Leroy Jethro Gibbs, played here by Austin Stowell.
