Golfs aren't really pretty. They're a bit dull. They spend ages designing them to look dull.
When the mk6 was released the iconic mk5 suddenly looked a bit dated. Now the mk7 is released the mk6 looks dated.
It's not prettiness, it's the cool design features that make the mk7 so much better than the mk6.
The things that I like about the mk7 GTI best are the little bold lines in the metal that remind me of the fact this car actually looks like those pencil renderings the car designers submit when they first pen the styling exercises for the new model. The only thing missing from the finished article is the 20 inch alloys and zero gaps between the tyre and wheel arches!!
I love the 3 door design on the mk7. So much so that I have insisted on a 3 door despite needing a 5 door. With some big wheels the mk7 is going to look darn near as cool as a Scirocco but without the Scirocco's shortcomings (and it's bulbous derriere).
In fact my only reservation about the mk7 GTI is that the mk7 R will be a trouser tenting moment...
