I'm bothered. I was less bothered by the lack of Ben in Homecoming, but I think we should get some time dedicated to why Peter is Spider-man and why he believes in "with great power, comes great responsibility". Though I'm more worried about the lack of Daily Bugle and Jameson. I don't want to see them skip over something essential to the mythos. Same with them skipping Harry and Norman. Granted they don't want to redo Goblin for a while, but the longer they leave it the harder it will be to introduce major aspects of the mythos.
