This movie is flawed-
a) JJJ knew that MJ left his son to be with Peter? What happened with his son, didn't even try to get MJ back?
Who cares?
b) Connors should at least make some kind of relation between the black goo, and the fact that Spider-Man turned black and more agressive.
why? Spider-man has always drawn a negative image in the press, why would he think Spider-man is more aggressive. How would he make the connection between black clothes and the alien goo?
c) MJ knows that Norman Osborn was the Green Goblin?
Um, yeah I think she probably figured that out.
d) Why did Bernard wait so long to tell Harry about something he knew about Norman's death? What does HE know? Yes, it was his glider, but so what? There's something here I don't understand
"I've seen things in this house I've not spoken of.....I know you're trying to defend your father's honor". i.e. your father was a crazy SOB, and I didn't want to ruin your image of him.
e) In the first movie, why didn't the burglar said something like "I didn't kill him" or whatever?
Because they were working together, and he had no idea if Marko was caught as he just took off.
f) Connors isn't a biologist?? WTF?
Yes, established in 2nd movie. Biologist don't teach cirtuit theory, "When Tau equals zero the eigenvalues are?"
It's more important to establish that Peter is a physics expert, when he is talking with Octavious, than it is to establish anything with Lizzard, who may never appear on screen.
g) How does Venom knows about Sandman's daughter? As far as I know, Spider-Man didn't know about that, so why the symbiote should?
Brock that knew that, or studied up for his revenge plot. There's nothing established in the movie that the symbiote is sentient, only that it amplifies agression and is a parasite.
Much more believable in parasitic alien life rather than some sentient being that's existed for millennia. That's why there's no "We are Venom!"
h) What happens after Venom's transformation? He knows Peter is up there in the bell tower... Peter is perhaps naked up there... where does Venom go? Where does Peter go? MAJOR PLOT HOLE in my opinion
Peter goes home and takes a shower, Venom goes and captures Mary Jane. Pretty well established that Brock wants to humiliate Peter, and not simply kill him.
i) Flint Marko turning into sand... except for the daughter's chain
If you're going to nit pick about physics then you may as well not watch any of the movies, and turn on the discovery channel.
