I'm not going to ask you what the **** is wrong with you, but I am going to address some of the things in your rant.
First off, War Machine is an Avenger in the comic books, but the movie universe is entirely separate and different. He is not now a member of the team. Tony Stark, the inventor of the armor technology, was recruited long before Rhodey took the suit he now wears. So Iron Man is the Avenger, which is what one would expect from the prequel movies.
Pepper is in the film because she and Tony are lovers and she lives with him in Stark Tower. Rhodey, on the other hand, is a military officer with a career and life that are separate. The action in the movie takes place at a rapid clip. Rhodey is presumably far enough away that he could not have gotten to New York in time to assist with the battle there. Though the combat is localized, at the end the audience is shown that the true menace is in fact global in scope. The invaders are simply coming through that one small portal/wormhole and being met with stiff resistance by the team.
Frankly, while I was watching the movie I never once thought about War Machine, despite the guy sitting behind me wearing his armor.
As for Rhodey being a hero of color and that being a bigger lure for Black audiences, that might be the case. But I am Black and I'm also about as big a comics nerd as you can find, as are my siblings. The audience I saw the movie with had many Black people in it, including the aforementioned War Machine cosplayer, a woman in a Photon costume and a Black Doctor Strange. (They came together along with a Black Widow.) It was an audience full of Black folks and nerds, and nerdy Black folks, and none of us were upset about Rhodey or the racial composition of the team that I know of. Do I want to see War Machine, Photon and other characters of color in future sequels? Of course I do. Did their absence bother me at all? Hell, no.
When you see the movie you may well sit there fretting and fuming over War Machine's absence, but most people won't. Watching The Avengers is an engrossing experience. If you can tear your attention away from the action on the screen long enough to think about anything else, you're doing it wrong.
Know what?
I actually don't give a damn at all that War Machine isn't in the movie. They made it clear early on that he wouldn't be, and I said, "oh well" and moved on.
And I strongly doubt it's going to be a make/break issue for more than maybe three or four people on this planet. But it *is* a simple continuity question in attaching the Avengers' place to the rest of the MCU (which is what the hype has been about all along, n'est-ce pas?), so it's natural that it's a question that people will occasionally ask from time to time, including me, including Howlett, including (no doubt) the guy in your very audience who dressed up like War Machine.
And the fact that Marvel *has* chosen to address some of the cross-franchise continuity issues in the movie (Jane Foster, TIH's battle at the college and in Harlem, Peggy Carter, Pepper Potts, etc.) means that it's natural to expect a mention of Rhodey to explain his absence. In the interest of equal time, you know? War Machine is a *lot* more important and canonical to comic-book Avengers than any of the "muggle" girlfriends like Peggy, Jane, and Pepper, so he at least deserves a mention, don't you think?
This is not a deal-breaker to me, by any means. I'm not "whining," although that's exactly the way all of you like to portray *anyone* who dares to question the infinite wisdom of Lord Feige or Lord Whedon. I'm just asking for a mention, same as the girlfriends got, and I don't think that's asking too much, and I sure as hell don't think it's a silly or dumb question to ask.
What I *do* get up in arms about, however, is the hypocrisy in people who blast Nolanites for jumping down the throats of anyone who dares to question the infinite wisdom of Lord Nolan --- and yet they do the same to anyone who has any question or complaint, no matter how minor or insignificant to others, about a Marvel film. The way you guys continuously ridicule and insult people like JHowlett and AB and even myself for bringing up
any concern about a Marvel film is just amazing. I thought this was an open forum to discuss *all* sides of an issue, but some of you treat this like religion or politics or (god forbid) sports, and go all jihadist on anybody who dares to share a different opinion than you.
