Other mistake: Black Widow and her sister steal a BMW. Getting away they damage the left rear quarter. A few cuts later they show the car again and it has no damage to the left rear quarter. (00:40:15)
Other mistake: Throughout the movie, the timeframe of Ikaris and Sersi's relationship seems to constantly change; their first kiss is in 575 BC, but Phastus in 2020 asks her how could she stand him for 5000 years. Sprite tells Dane that they broke up 100 years before, but he leaves her because he can't stand to keep secret from her the mission. Which is a problem, since he mentioned that Ajak told him that when they left Babylon, so around 500 BC.
Other mistake: Sandman AKA Flint Marko is the first of the villains to be changed back at the Statue of Liberty fight, and he is told by Peter to stay inside the head to be safe. Seconds later Electro discharges a massive electric surge onto the statue head, which is made of bronze, which is a good electric conductor. Marko should not have survived that. (01:47:40 - 01:48:10)
Suggested correction: It's made of a good conductor that would protect him like a faraday cage if anything. (Almost) all the energy would go through the metal, not the less conductive person.
A faraday cage is very sophisticated, calculated, engineering to block electromagnetic fields. You can't accidentally have a faraday cage.
