I love Bones for many reasons. It is far from the best show ever and has it's share of flaws, but it has a delightful cast of characters, leads with great chemistry, and very good, fun dialogue.
But most importantly, it lets me refer to grown men as "smitten."
1. Seeley Booth
Booth does not "like" Bones and he does have a "crush" on her. He flat out adores her even when she drives him crazy. More than anyone else, Booth gets there's never any intentional arrogance to Bones, and that the (often inconsiderate and inappropriate) things she says are Bones really just trying to understand what's going on with people and their lives. He's completely unthreatened by her intelligence and the only thing he wants from her is for her to be herself. Moreover, he respects both her brain and her ability to take care of herself. He knows that if she's there, she has his back, and when he asks her to stay behind and out of the line of fire, it's not because he doubts her ability, but because there's another job to be done that she'll be better at than him, or because protocol and regulations say she can't participate.
2. Jack Hodgins
Jack and Angela were very out of nowhere which seriously threw me, especially as the first episode of the season treated it like it was something we should already be familiar with from the season before. That and the fact that they seemed to move too fast and be too forced at times keep me from really shipping them. However, they're very cute together, and Hodgins's near absolute blindness to everything but Angela is positively darling(and he was already the world's most endearing conspiracy theoriest.) I concede to having a big goofy grin throughout the aborted wedding.
3. Zach Addy
Bones's former intern, now a full blown forensic anthropologist. His combination of schoolboy crush/hero worship of Bones in S1 was positively darling...I shall always treasure the contemplative look on his face when he learned that Bones had a "personal" relationship with her own instructor. Sadly, he seemed largely over it this season. I think, though, that he just learned how to suppress it...
And to go off to a completely different subject: I flat out love Max. I have a thing for families on opposing sides of the law, with the party on the wrong side having a borderline obsessive need to protect the other. Max knows that being who he is makes a real father/daughter relationship with Bones impossible, but he keeps hoping. He unhesitatingly destroys anyone who may be a threat to his daughter even iif it means driving her away, because the important part of "alive and hating him" is "alive." He and Booth like respect each other, and they should. Max not only expects Booth to try to arrest him, he'd be pissed off if he didn't. He likes Booth because he views Booth as the perfect man to protect his daughter, and a large part of that is Booth's principles. The main difference between the two men is that the side of the law they started out on determined whether or not they crossed the line. Max has long since crossed the line of no return. When Bones needs Max's help to save Booth, Max sets to it with the same singleminded obsessiveness that he applied to eliminating the people who would hurt his children, an obessiveness that matches Booth's protectiveness of Bones in similar situations. The things he does that upset Bones are little more than extreme versions of things that Booth has done when Bones has been threatened before. There's absolutely no doubt that, had it been Booth doing the hunting and Bones in danger, he likely would have done the exact same thing.
