Hey kids, do you realize that the Spider-Man movies are in a different universe than the Amazing Spider-Man comics? Do you realize that this means that Gwen Stacy doesn't have to die and Venom doesn't have to say "we"? Do you realize that critiquing stories based on versions of that story in other media merely because the story is different is an argument with no validity?
Sure, an argument like "It is cooler when Venom says 'we'," is okay, but the mere difference of facts is not a fault in and of itself.
P.S. One of my favorite series right now is Spider-Man Loves Mary Jane, wherein Gwen Stacy is quite alive and well! :D
