My thoughts here are pretty much the same with most adaptations of comics... "why'd you even bother? If you didn't like the story in the first place, which apparently you didn't" Like you pointed out they took out elements that added heart and impact and emotional connection for the viewer.
You'd expect, and I could understand...changes to bring things closer to reasonable for the modern audience ...like having the Spider change Peter Parker's DNA instead of it just being radioactive. But more and more I see changes just for the sake of making changes.
