"County Crossover" contains one of those types of story tropes that doesn't always appeal to me, with the risk of being too one-sided or sleazy. It was relatively common with the 'Law and Order' franchise and there were numerous cases where it was done well (more early on than later). Did like the basic concept however, although it isn't novel that has very rarely mattered, and anything centered around the music industry immediately grabs my attention.
On the whole, "Country Crossover" was a very good episode. Despite one aspect bringing it down somewhat, it is for me evidence that Wheeler was an under-estimated character and that her chemistry with Logan was good. If anybody disagrees, that's fair enough. "Country Crossover" could easily have been too sordid or gone overboard with the sleaze factor, which a few previous 'Criminal Intent' episodes did do, but just about didn't.
Production values are slick and professional, not ever resorting to cheap or untested gimmicks or anything. The music is haunting in the right places and isn't constant or too loud, and the direction gives the drama urgency and breathing space. The script is tight and thoughtful, not getting too smutty or overwrought. Including some dryly humorous lines from Logan, like the one regarding the cocaine.
Actually like Wheeler and liked that she was understated and a more sympathetic contrast to Logan, without going too far that way that she risked danger of having little personality. Julianne Nicholson and Chris Noth, on excellent form, have nice chemistry and interact well. They may not have the same playing off quality that Goren and Eames' chemistry has but it is always nice to see how Logan and Wheeler work individually and as a team, their attitudes towards each other and basically their whole dynamic. The supporting performances are fine, Kohl Sudduth expertly making one unsure of whether he is guilty or innocent.
However, the ending for me didn't quite come off. It has too much crammed in and moves too rapidly, making it on the confusing side. Haven't warmed to Ross yet for reasons said in previous reviews.
In summary, very good. 8/10
