Did Cap seem "over-powered" a bit in this movie? I've never taken for him to be "super-powered" but just "absolutely powered." He's at the peak of human endurance and physical strength and maybe a nudge better. The fastest a person has ran a mile is 3m43s. So, Cap can probably do it in 3m30s. Maybe 3-minutes flat on a good day.
His stamina, endurance and healing are all "peak" too, again giving the movie world a good deal of latitude on what that entails.
But in this movie... Well, see him acting like Superman. The biggest thing for is when he's stopping the helicopter Bucky is trying to escape in. I don't care how strong Cap is, he doesn't weigh more than a helicopter and certainly not more than a helicopter taking off when it's providing enough lift with it's rotor to achieve take-off. But we see Cap run up to the helicopter, grab the skid, and tug it back to the ground. Which.... No. If the helicopter is lifting off the ground a 200lb man isn't going to just tug it back to the ground, he's going with it. Same with when we see cap grabbing on to the skid and rooftop helipad. He's straining, sure, but he's pulling a several-ton heavy helicopter, achieving lift, towards him and preventing it from going away.
That seems a bit strong for Cap who, again, isn't supposed to be strictly "super" powered, and there's not enough hand waving in his abilities to "buy" him the leeway. I mean, strictly, Superman wouldn't be able to "pull" a helicopter to the ground if it's got lift (again, Superman weighs less than a helicopter. He's going with it no matter how strong he is pulling it back to the ground) but there's enough mumbo-jumbo in his powerset it's argued that some aspect of his flight, strength, sun-powered powers allows him to "fix" himself to the ground in order to pull the copter to the ground and prevent it's takeoff. (He's "flying in reverse" in other words.)
Cap? He's a regular, squishy, human. He's a very, very strong human who can do a lot of amazing things, but he's not stronger than a helicopter engine which is moving a several-ton heavy machine and keeping it in the air.
I was wondering about that. I can only think that, because it was a HYDRA hit, they manipulated any investigation, likely via SHIELD.
True, but then wouldn't Tony have access to SHIELD's/HYDRA's info after JARVIS broke into the Helicarrier's computer with his little thumb drive, or when Black Widow released the HYDRA files? (Though, I guess ZImo apparently needed Bucky to tell him what happened on that date. But I'm not entirely clear on why that's the case. If the files were too encrypted for him or if they weren't there. If they were too encrypted I'd think JARVIS or FRIDAY could've hacked through them.)
