I think Agent Coulson was really annoying and I'm glad he's being left out of the movies now. Not a fan of Kat Denning's Darcy either.
Ditto. Coulson came across as very smarmy in his Thor, Iron Man and Avengers appearances, and it detracted from the Avengers that he was chosen as the one to 'avenge,' since half the team didn't seem to like him very much (Natasha openly disrespected him, Cap looked like he wanted to squirm away from him, Stark quipped that it was a shock that he had a first name and wasn't just 'Agent').
While I didn't mind Darcy, since, to me, she should have served the role the General (played by Tommy Lee Jones) served in the First Avenger, the guy who says the funny things that straight-lace Cap wouldn't say, being the humor-gal to a more serious Thor. Unfortunately, we got Darcy *and* a quippy gleepy-eyed Thor, which I did not like at all. Thor, like Cap, should have been played straight. On Earth, Darcy and / or Solvieg can lift the funny lines (or someone funnier could have played Jane...), in Asgard, that's pretty much what the Warriors Three are for (particularly Volstagg and Fandral, since Hogun's known for being pretty grim).
Thor's quippiness, and Thor being the butt of humorous scenes (getting side-punched by the Hulk, for instance), dragged down the Avengers, a movie I otherwise *loved.*
The entire 'bilge-snipe' conversation between Coulson and Thor was probably my least favorite scene, since it had both 'sucks all the super out of the room' Coulson, and quippy funny Thor. Cinematic Stark is a quip-machine, as is cinematic Peter Quill. That's established, and it doesn't bother me. But I want my Captain America and my Thor to be quiet, serious badasses, not 'funny guys.' (That said, MCU Stark being 'the funny guy' means that MCU Hawkeye is *not* the same quippy character he has been for decades in the comic books, and, combined with some lackluster writing, and an actor who has all the charisma of a box of noodles, MCU Hawkeye is just deadly dull, and I would have breathed a sigh of relief if Quicksilver had saved the child, but not Clint, in Age of Ultron, since it would mean we wouldn't have to see any more dull Hawkeye scenes.)
It's not at all the comedy I disapprove of, and even Coulson didn't ruin my favorite funny bit, the banter between Stark and Pepper at the beginning of the movie, which was awesome and appropriate in it's place. In it's place, the humor even in otherwise serious movies like Winter Soldier (Nat flirting with Cap, or bantering about setting him up with various women), helps to both characterize folk and lighten / humanize the movie. Deadpool was practically a joke-vehicle, and I loved it. I'm all for it, as long as it fits both the character and the tone.
