Pottermore is driving me potters!

I'm struggling to understand what all the hype is about. I'll admit that I've never really got into the books but, having enjoyed the movies (a lot) I was looking forward to being persuaded to enjoying the writing as well. I signed up and began exploring the first book. To be honest, I found it a little boring. I wanted to explore, but all I seemed to have was the ability to zoom in and out. I wanted something interactive, but it seemed to just give me disjointed bits of story.
Am I missing something? Help!
