I have always loved buddy movies and buddy TV shows and I think the whole thing started with Starsky & Hutch. I've been watching them again lately and holy crap is it not PC and the disregard for police procedure is insane but what is still great is the interaction between the two men. Again, there's a lot of hugging and touching for nineteen seventy whatever it was and though the women in their lives come and go, they are 100% committed to each other. All these things stick in the psyche and for me, were just waiting to come out on the page.
In Grimm, the best relationship Nick has on the show, and it's going on 6 years now, is with Hank. He has no chemistry at all, nada, with any of the female leads. Watch if you don't believe me, but with Hank, there is fondness and dependence and trust. It's always, I'll get Hank, I'll call Hank, and that's one of my favorite things to watch.
There's a difference, for me, of the bromance that I'd like to think will lead to true-romance and the kind that I don't see making that leap. Danny & Ray in Running Scared, no, Starsky & Hutch, yes, Dirk & Al, no, Franklin & Bash, no, Nick & Hank, no, Steve and Danny...oh yes, HUGE yes.
