^ What if Supernatural nerfed Satan's power, told him he was a long lost Winchester brother, then make him a good guy, then made him a bad guy again, and then nerfed the power of the one person who could defeat Satan, and then had other characters go on a separate side mission that has nothing to do with the actual plot? Would you like it more then?
Milo......oh, Temis shakes head.....how can anyone find Milo Ventimiglia a more watchable actor than Ackles and Padalecki?
I'm not talking about looks. I'm talking about having an ounce of talent or charisma. It's Milo. 
Surly little Jess from Gilmore Girls with the floppy hair. Quinto's got some talent, but Milo..... 
Milo Ventimiglia as Dean Winchester. Time is spent on it because the writers are invested. When Sam and Dean do nasty shit to each other, they actually interact and say nasty things to one another, (complete with knife throwing and attempted strangulation) unlike the brothers Petrelli when one brother shoots the other and then they never mention it again. Oh boy, do the Winchesters ever mention it and then some. That final scene last Thursday was brutal.
Cuz he just is.
I dunno, I guess I like em cute and dumb. Well that makes no sense, then how can I be even more obsessed with Michael C. Hall? I like variety. That's my story and I'm sticking to it! Which is why, if the relationship just falls flat for you, the rest of it doesn't make up for it, and there's no reason to watch.
Whatever it is, if it doesn't manifest itself immediately, it ain't there. Just accept the fact that it's not something that's going to exist for everyone, and is very much a matter of taste.
If you don't see the bond, then you don't see it. No harm done. If you'd been there during season 2, (Dean refusing to kill Sam during his possession, then punching him out instead of an angsty reunion scene at the end was a classic) I think you'd appreciate it but c'est la vie. At least Heroes could have had the decency to set Adrian Pasdar loose. He'd have been terrific as the second of the four horsemen of the apocalypse. Titus Welliver is playing the first one. He's up very soon. Actually, Pasdar is the only other actor I can think of who could have pulled off the part of slimy Zachariah, the angel dick.
I could see a more modestly talented actor managing to do something with that role. Dex would probably come off as more akin to the character in the novels, who is more authentic as a serial killer (genuinely emotionless, not just a guy obviously repressing his emotions) and less sympathetic. It just wouldn't be the top-caliber show it is now. The novels are readable, after all, just not compelling.
I'm still waiting for good explanations why Peter thought it necessary to play with fire and get Sylar's power (which he never actually did anything with) and why nobody remembers his poor old Irish girlfriend.
