Agreed. The adjusted icons are better only when compared to the terrible icons Google released. They are all pretty bad though.

> the geometry is too big

I agree, and find it even more difficult to understand this design direction in our age of ever increasing screen resolutions.

Unless I'm misunderstanding your comment, it seems the old and new icons are just about the same size.

The feature sizes of the icons, as in the paths and shapes that make them up are too big. they're harder to discriminate when you shrink the icon down.
