Considering the more "scienitific" aspect of the of this universe, having Rhino being bombarded with radiation wouldn't make any logical sense, considering Peter wasn't bitten by a radioactive spider. That's always been changed to a genetically altered spider because it's less "60s-like", otherwise why wouldn't he get cancer? Spidey's origin was changed in TASM to something that was more connected, so why not make Rhino's origin something that has impact with the actual movie, since you know typically supervillians origins have ties to events in the plot or the main character, it doesn't typically ever just randomly happen, which IS lazy writting. Spider-Man is also a MUCH more fleshed out character than the Rhino, only important aspect about Rhino is that he's big, stupid, and violent. As long as whatever happens to him to become Rhino is something that HE got himself into out of ignorance, that's all that matters, not how it actually HAPPENS, since in the comics it was just some random mobsters. This is a movie, not a comic book, things are going to be more interconnected, since movies aren't episodic like comics. Directors also have different interpretations and styles they bring, which they SHOULD be allowed to do. Respecting the source material doesn't mean you have to wh*re yourself out to it and do all of it's bidding just because some people on the internet (the miniority) think so.
