This episode fell decidedly below average on the scale. Simmons' sub-plot was so pointless that it detracted from the search for the UnSub. It feels very much like he was given this personal focus simply because everybody else got one. There was nothing particularly engaging about the family dynamics even though Daniel Henney tries quite hard. I think this is largely to do with the fact that there's no real story there besides "Dad's on duty while Mom gets some rest!" I will say however, Henney has a very easy charm on screen. Of all the new team members, I fell immediately into place with Simmons because his character was written like a place holder. Brought an interesting set of skills and an established background but no real insight into him as a person (except for the one episode where his wife was taken hostage). He's relaxed, charming, smart and talented, on top being very easy on the eyes. But that's it. As a result, his sub-plot that focuses on him as Matt and Dad was just a wasted opportunity.
Though the case was based on an interesting premise, given how quickly this team has put clues together before, the deduction just did not come close to the expected mark. I definitely zoned out of the episode a few times because I was just plain bored.
Season 15 does not seem to be doing that great.
