1) Fighting is not just about brute strength. How did Steve Rogers learn how to fight so well without any unarmed combat or martial arts training?
2) And where the hell did he learn how to pilot a plane?
3) Why was Hydra's technology in the 1940s even more advanced than what we are using now? They have laser beams that obliterate humans totally (nothing left, not even a speck of dust), turbo cars, aircrafts...
4) It's amazing that Steve Rogers could infiltrate a heavily guarded military base easily despite not having any stealth training, and also despite carrying a frigging bright red and blue shield on his black which simply yells "SHOOT ME".
5) Despite saying that he does not like to kill people, Steve Rogers seems to show no hesitation (and no qualms) in throwing his enemies off a plane in mid air.
By the way, Chris Evans (the main actor) also played Human Torch/Johnny Storm in The Fantastic Four, which is also in the Marvel universe. Does this mean that future Marvel movies cannot involve both Captain America and the Human Torch together (unless he is in his flame mode)?
I am also very curious on how they managed to make Chris Evans look so skinny and scrawny. It's probably due to CGI - I am guessing that they used a puny actor for his pre-Super-Soldier-serum role and matched Chris Evans' head in. But it's really impressive and realistic!
As of 31st July 2011, Rotten Tomatoes gave it a certified-fresh rating of 77%. I think the most I can give it is 6/10. And this score because I am a Marvel fan.
