Hmm...now thats a good question though...
To think it now, yeah perhaps thats because in comics lore, they already being set up as the Avengers "Big Three" so my brain has been set to accept them as they are in the comics.
You have a solid point there though..once again, thanks for your input
Maybe my issue with BP-CM-DS as "Big 3" is (like Docker2.0 stated) that we barely see them together, let alone interact with each other. But the same can be also said with IM-Cap-Thor at the beginning. So, lets hope we have a writer who understands these character dynamic like Joss Whedon did in their first interaction.
On the cast thing, while I agree that Benedict, Chadwick and Brie are better acting wise than Evans and Hemsworth, but chemistry wise, thats different thing, though...
Again I'd like to point it out that one other thing that makes the Original Big Three feel special is because the chemistry on and also off set between RDJ, Hemsworth, and Evans (not only those 3, but with the cast of other Original 6 as well) was so natural. You can tell that they are really close friends by listening their interaction on and off set.
Yes, I know, it is too early to tell but I knew that few fans here had many issues with Brie's Carol as many has stated her performance as stiff and wooden. And despite Black Panther doing great in box office, I dont think that Chadwick's T'Challa has become an instant fan favorite (as many said that he is being over shadowed by his co stars in his solo movie) or general audience favorite as well like Evans or Hemsworth did in their first solo movie.
For Benedict, I also aware that a few fans also has not like his Doctor Strange performance until Infinity War.
My point is that, despite they are indeed a better actors, but Benedict, Chadwick, and Brie has more mixed reaction regarding their performance than what Hemsworth and Evans did.
But like I said, it is too early to tell as they have more sequels coming up for them... lets just hope we have a writer like Joss who get and understand each character's dynamic, if Marvel Studios can do that, then I believe we can have a natural and good chemistry that we can love and cheer like the Original Big 3 did.
I personally loved each performance in their solo movie, though.but yeah, their lack of interaction or the charm and chemistry is the other things that I think they still cannot be matched with the Original Big Three. Time will tell though.
Btw, nice to have this discussion with you...I never been this long for discussing on this forum. I learned so much. Thanks again for your perspective there..
(also apologize if I have some grammatical error, ...but i did my best there, haha)
