Okay, you're right, that was an unfair comparison. Overall I enjoyed the Winter Soldier more than I thought I would (you kind of have to go in with lowered expectations when he's one of the least-powerful Avengers that actually has powers).
Firstly I was looking forward to Cap having a love interest after Peggy. Instead they not only creeped me out by having her on her deathbed, and the Agent 23 character played by Emily Van Camp could just as easily have not even been used in the movie. I HATE when they do that with characters, Iron Man 3 was the worst example of name-dropping and not following through. But I already ranted about that.
Secondly, Arnim Zola's character was a complete 180 from First Avenger. He was genuinely bothered by all the wrongdoing of the Red Skull and had no real loyalty to Hydra. Then all of a sudden he's their bitch boy helping them take over SHIELD? I call bullshit on that. I know he's supposed to be a villain in the comics but if they were going to play him that way then they shouldn't have given him any redemption or anything like that in the first Cap movie.
Thirdly, what the fuck was with Falcon? He's a dressed-down War Machine who was supposed to have powers and they totally fucked him. What, are they afraid to give a black character any actual superpowers? Pisses me off. Mackie even said they were supposed to give him the bird-telepathy power but it never went through.
Fourthly, way too much suspension of disbelief as to how normal humans are supposed to shake off otherwise crippling or fatal injuries. There's too many instances to name but if you watch the "Everything Wrong With" of the movie, you'll get what I'm talking about. But ESPECIALLY about Bucky, that was just...I even wrote in a way he could survive plausibly in a script edit that also explains why his arm is lost, instead of them having to saw it off for no good reason.
Fifth, instead of keeping the cool scene with the old woman on the council totally kicking ass, they ruined it by having it be Black Widow in disguise. Not that the disguise wasn't cool but they could have saved that for another scene, perhaps letting Agent 23 use it and make her more prominent in the movie like she deserved. Kind of hard to look at Cap and wonder if he's still a virgin (and that's not really too ambiguous).
Sixth, it totally ruins Agents of SHIELD (which if I were in charge of the TV stuff, I wouldn't have done anyway.) Plus the aftermath makes no sense and puts their best people out to pasture. And I call B.S. on Rumlow surviving.
So that's the major complaints. I have more but these are the big ones. I easily remedied them with a few edits to the script but too little too late. It's just for my own edification.
