Because I live outside a very small town where many people don't have computers and those who do have somewhat intermitent internet, NETFLIX hasn't really caught on here. We therefore still have a privately owned DVD rental store. MI-IV Ghost Protocol was still on the new release shelf. Okay, it's not a very good DVD rental store but it's the only game in town...
William Brandt is IMF's top anaylst. He's riding with the Secretary (yes, the definite article) when he meets Ethan Hunt. In the next few moments, the Secretary is dead, the driver is dead, and Brandt and Hunt are in the bottom of a river, or a canal being shot at by men on bridges, the bullets behaving in ways that Mythbusters proved they don't. They get away, do some funny schtick with pillars and a moving train, then Brandt puts on a blue henley and looks amazing. What? I'm not watching this thing for the plot. Then he looks amazing in grey suit pants and a white shirt, and saves Hunt from splatting down a few hundred stories in Dubai by nearly throwing himself out a window and allowing Hunt to climb up his body. Hunt is not as grateful as I am. (Also, the women in this are great and it passes the Bechal test.)(Seriously Joss, you couldn't have had Hill and the Black Widow talk? Once?)(Where was I...)
Then there's a extremely competent fight in a silver grey suit where I may or may not have popped an egg. Oh noes, Brandt is not merely an analyst he's a man with a tragic past that intersects with Hunt's past. Because Renner has that tragic past squint down. Then there's banter with Simon Pegg's character Benji, some fascinating lunges before throwing himself down an air shaft, and a little sweat. I think I need to see Renner do comedy. There's a fight scene, more competence, and forgiveness for that tragic past intersection with Hunt.
So, to sum up: suits and competence. William Brandt is essentially Phil Coulson Mark One. Or Junior. And fandoms intersect. Given fandom, the intersection probably involves lube.
Also, there's this...
...specifically this...
...and therefore your argument continues to be invalid.
