This thread is helping me deal with IMDB boards going away. Hard to believe that in 2017 there are still people who think "losing to a girl" is a problem.
I chose to reply to the only poster I respect in the thread (though I didn't read all comments).

I could be mistaken, but I'm beginning to think you're struggling with the concept of a
girl
kicking some guy's arse. You know, almost as if that's entirely impossible unless there are some special circumstances or something. Did I read you right ?
Fabricati Diem, Pvnc !
RIP Terry Pratchett

One last time since the boards are closing down soon:
Obvious troll is obvious.
Ah that felt good.

Facts of the comics are not always equal to the facts of the movies.

I had read on one Marvel site that Hawkeye's fighting skills were ranked higher than Black Widow (and Wolverine, for that matter). They might be basing this on older comics, though. Regardless, one factor that the OP failed to take into account is that Hawkeye is exhausted by the time of the fight. Even factoring the two of them at the same skill level, Black Widow had the edge. I would even say that the only reason she didn't win the fight sooner was that she was working to stop him and not seriously injure him.
I was also so glad that they stayed away from Black Widow and Hawkeye as a romantic couple, in general. Having a romantic twist in the context of the fight would have been beyond idiotic. He was mind-controlled at the time.

"Russia's Red Room assassin program"?? That's just made up. I don't recall anything in the movie taking about some red room program.
Not made up in the least. The Red Room program is character background that comes straight from the comics (
http://marvel.wikia.com/wiki/Red_Room
) and Natasha herself mentions it in the next Avengers movie (Avengers: Age of Ultron. Plus how the Red Room was run back in the late 1930's was also shown in Agent Carter season 1 episode 5 "The Iron Ceiling"). So that she's a product of the Red Room assassin training is in fact film canon.
And again this is not some girl who decided to take up cross fit beating a guy.
She. Was. Trained. To. Be. A. Frickin'. ASSASSIN!!!
one of Russia's elites. Perfectly believable that a
highly trained assassin

• regardless of gender - would be able to kick someone's ass.
  It would have been more believable if they were fighting and he was getting the edge in it and then maybe they turned it into some romantic fling between the two. Now that stuff happens ALL the time
  Because that type of stuff happens all the time is the exact reason why I'm glad they DIDN'T do it.

Oh come on. Sure, maybe she's more than an average girl. But, like a girl who takes up cross fit or something. she's still not kicking a dude's ass. It would have been more believable if they were fighting and he was getting the edge in it and then maybe they turned it into some romantic fling between the two. Now that stuff happens ALL the time and it would have been more believable.

I saw him interviewed by Bawbaw Wawwaws.

Who is JW? Jewemy Wenner?
Are Bawwy Kwipke?

Well, you know JW had to be embarrassed when he read the script and saw he lost a fight to a girl. Never mind how many millions of $ he was paid for it.

Her name is not BW BW is just what fans tend to use on the internet instead of typing out her code name fully all the time. Her code name is Black Widow. Her real name is Natasha Romanoff.
Also, she's not just some girl. The character is someone who was raised from childhood in Russia's Red Room assassin program to be one of Russia's most deadly assassins. Losing a fight to her is nothing that a friend of hers (who knows what exactly she is) would be ashamed about because she's not an average girl.

I admittedly didn't know her name was BW. The other poster told me her name when I was calling her the girl avenger. I just couldn't remember her name. My only point is that if the director is going to name her BW then he has to understand that's not too memorable of a name to begin with.
A name of two initals is not common

Clearly the director didn't care too much if he's going to give a girl character a name that is ONLY INITIALS.
When did he do that?

Listen, it has nothing to do with the fact that this BW is a girl
Yes, it does.
imagine having to be Hawkeye losing to a girl
Like I said, they're not 12 years old, so they don't worry about losing to a girl.
Seize the moment, 'cause tomorrow you might be dead.

Guy, dude come on, man. THat's NOT what I mean.
I'm talking about losing a fight not being close to a babe like the gal that plays this BW.
She is undoubtedably cute.
Listen, it has nothing to do with the fact that this BW is a girl and that she's getting close to Hawkeye.
You guys are just getting mad at me because I didn't know her name was BW. You think that would even stand out in a movie? Clearly the director didn't care too much if he's going to give a girl character a name that is ONLY INITIALS.
"Hi, I'm JH." Come on. Don't act like I'm the ONLY one to think that's goofy.

You know the other actors were ribbing on him for that.
No, they weren't because they're not 12 years old.
Ewww, girl cooties.
Seize the moment, 'cause tomorrow you might be dead.

Hey! What was that for?!

You can't win because you are a loser. You don't know the characters strengths, so you go on about that. Then, you make it about the actors - like losing a fight to a girl on-screen would bother him?
Rule of thumb, when you make a thread and more than one person calls you out for being stupid, you are stupid.

I can't win with you!
I'm not saying the ACTUAL gal playing the role. I'm talking about BW! The character.
There's a big difference.
I am certain the gal that plays BW is a great gal.

What?! I wasn't bashing the her.
you lose to a girl in a fight???
I mean the actor. I'm not trying to be rude, but just imagine when he reads the script? "Wait, so I'm supposed to go toe to toe with some girl avenger?? and lose?!?!?!" LOL!
You know the other actors were ribbing on him for that.

What?! I wasn't bashing the her.
I didn't know her name was BW. She just wasn't that memorable of a character.
But seriously though. Some girl is just not going to be able to put a beating on a dude like that. But, maybe if she was a greater fighter is says a lot about him. because he did kind of take her through the paces a bit. I mean, a skilled man in hand to hand would have probably marched through Hawkeye. but BW was kind of life and death there for a bit.
Still though. I'm not talking about the movie character. I mean the actor. I'm not trying to be rude, but just imagine when he reads the script? "Wait, so I'm supposed to go toe to toe with some girl avenger?? and lose?!?!?!" LOL!

You obviously don't know the powers and strengths of the characters. BW is a much more skilled hand-to-hand fighter than Hawkeye is.
Of course, your constant referring to her as "girl Avenger character" shows you have issues with women in general. I'm guessing you can't get a date other than on Skype?
