Personally speaking (and I am fully aware that it's a subjective thing) the only wow factor is "Wow, what were they thinking?".
They were thinking that it is a beautiful design. And, you know what, I think they were right.
I have a feeling people dismiss the "notch" just because it feels like a compromise (which is, for some reason, not allowed in Apple world), not because they genuinely dislike it.
As for the bump, it has a beauty-of-function look that I like.
Really, it's the best looking iPhone since the 4. Not sure where these negative feelings are coming from.
