First is that Marvel has a in-house team of action directors and guys like the Russo Bros. and Joss Whedon just handle the character scenes. Is this true? Is it common?
Grantland actually claimed that this is how Marvel does it? This is 100% false. Each movie has different directors/action directors/stunt coordinators, and, frankly, it shows. I think Cap2 is the biggest example of this, as it's action is completely different from the previous films.
If so I wonder if this would explain a lot of the scenes having a sort of redundant feel across the movies. It's starting to become a negative for me. The action scenes in Winter Soldier are way too similar to something like the Avengers for my taste.
Huh? OK, putting aside the final set piece for a moment, is there anything in Avengers that is similar stylistically and tonally to the attack on Fury, the raid on the tanker, or the mid-traffic attack? Heck, is there anything in Thor or Thor2 or Ironman? I'm really not seeing basis for redundancy.
The final set piece (the attacks on the carriers) is what it is. In any action film, the final action sequence will be big, brash, and over the top. However, what was distinctly different about Cap2 was that the story didn't come to a halt for the action to happen. The story was carried through the final piece, with everyone on the team having a specific task that needed to be achieved, and that task was NEVER 'kill the bad guy' (all too often, big final action sequences are solely fueled by that goal...which makes them feel hollow).
Another thing they bring up is how having this extended universe is sort of a detriment because in a movie like Winter Soldier there is nothing really at stake. We know they are all going to be back for Avengers 2. I think they kind of have a point, I mean, when Nick Fury "dies" did anyone honestly believe it? I mean, the moment it happened didn't we all just assume he was going to come back later in the movie? Of course. It was a given.
This I am more inclined to agree with....sort of. I agree that Marvel needs to do something that screams "noone is safe". Killing Thor would do it (as well as lead into some potentially awesome Asgardian stories). As for Fury, going into the film, I had only two things spoiled for me:
1. That what occurs in the movie changes the MCU in some drastic fashion
2. That there was something on Fury's tombstone
Now, it's Nick Fury. He dies pretty often, but doesn't die, that's pretty much law. However, it still made the attack on him and the assassination attempt very dramatic for me (especially when they didn't show his tombstone immediately after).
That said, what you're criticizing seems more to be the format of movies and the desire to reach a happy ending. The thing about a film is that, though you are an outside viewer, you should also be empathizing with the characters. While YOU know Gandalf isn't falling to his death at the Bridge of Khazad-dûm, the scene is still emotionally effective because you share in the loss the fellowship feels at that moment. There are a few movies that break this mold (Rocky, No Country for Old Men, etc) but, ultimately, we know going in that Sarah Connor will get away.
