When I see people arguing about Buck/Tommy and Buck/Eddie, I think of “Moonlighting,” another 80s TV show that the screenwriters are probably very aware of.
The first three seasons of “Moonlighting” were fresh and sexy and exciting. Then Maddie and David had their big moment (named by TV Guide as one of the Top 100 moments in TV).
It survived for two more seasons, but it never had the degree of storytelling and tension and ANTICIPATION that it had during the first 3 seasons. It no longer captured viewers because the story had reached denouement.
So, let Buck have his Tommy. Let Eddie have the rest of this season and into the next to figure out how to be alone (without looking for “a mother for Christopher”) and who he really is.
Let us anticipate the bang, rather than go out with a whimper.
