Corrected entry: After freeing himself from the symbiote, the symbiote begins to fall into the area where Eddie is. In an overhead view, the symbiote is seen rapidly attaching itself to Eddie's arms and covering them. The very next shot shows the symbiote rapidly enveloping his arms again.
Corrected entry: Never once in the entire movie do the three villains get called by their comic book names of Sandman, Green Goblin 2, and Venom.
Correction: Sandman is referred to as "Sandman" during the newscast right before the final battle and Spider-Man refers to Harry as "Goblin" while taunting him. (Albeit, something like "Goblin Jr, " but he refers to him as Goblin nonetheless).
Corrected entry: The Sandman and his wife both have blue eyes. Their daughter has brown eyes which is genetically impossible since blue eyes are recessive.
Correction: Both my parents and my sister have brown eyes, mine are blue.
Which is exactly the opposite of what the mistake is describing. If a child has a dominant trait, one of the parents would need to carry it and would not express the recessive trait.
Plot hole: When Harry's pumpkin bomb exploded, disfiguring his face, there were also more pumpkin bombs around him. This explosion should have caused them all to explode, which would have killed Harry.
Suggested correction: It's entirely dependent on how the pumpkin bombs function and how they're built. They're likely built to be able to withstand a certain degree of outside force and heat so they wouldn't just randomly explode during a superhero/villain battle. They also don't seem to function like regular grenades... there seems to be electronic components to them. So it's entirely possible they can't go off until they're activated because certain components inside haven't mixed or been armed. Their rules are just too vaguely defined for this to be a valid mistake.
Stupidity: After Harry threatens Mary Jane that he would kill Peter if she doesn't break up with him, she does what he told her to. Why didn't Mary Jane warn Peter about Harry? Did she forget that he is Spider-Man? Even though Harry was watching them, she still could have warned Peter.
Suggested correction: Mary Jane didn't forget that Peter was Spider-Man. A great deal of time passed between when Harry talked to Mary Jane and when she was forced to break up with Peter. During that time, Harry could have threatened to kill her family if she didn't cooperate with him.
Mary Jane doesn't take into consideration whether Harry would have the capabilities to kill Peter since Peter is Spider-Man.
Correction: Just watched the scene to check and this is incorrect. The first shot (the overhead shot) merely shows the symbiote grabbing onto his shoulders. We never see it covering/enveloping his arms until the second shot.
I have seen the scene to and the overhead shot does indeed showing the symbiote covering his arms and then covering his arms again when a close up of his transformation is happening. https://www.youtube.com/watch?v=oqdiN5cFgZs&app=desktop.
I just watched the link you sent. While it's true that his right arm (mainly the hand and forearm) is starting to be covered in the overhead shot, there's no inconsistency. The amount of symbiote on him is the same at the end of the overhead shot and the start of the next shot where we see him. So it's still not a mistake.
