Forgive the necromancing of this thread, if you please.

Iron man's voice, the masks, the quiver, war machine, black widow's accent.

These are all useless tweaks. I will not object to anyone making a fan edit their own vision. But I wouldn't like these changes. They are needlessly complicated from a special effects stand point and they don't return on that investment in my eyes.

Cap's suit though. What is that, spandex? My god if anyone was good enough to give him a more protective outfit that would be a super boost to my immersion. You even see it in the end battle where he's all scratched and such, and you just notice how thin it is, how flimsy. This is probably even a bigger job than the suggestions I commented on in the beginning of this post, but this I think would make a difference.

It would also be very nice if the "council" wasn't just a group of nameless international mooks just there to give us more tension, and the nuke. Making them a nod to other marvel works would be a nice touch. Still, not an improvement to the quality of the film.

Personally I would simply add in the 30 minutes of footage. barring anything that is completely useless or actually bad, I haven't seen it all.

Then I'd write a letter to Joss Whedon to tell him to not snip great cap scenes like that and give him a damn weapon and some actual protection rather than a gymnast outfit.
