I agree that some responses were a little over the top but disagreeing does not mean hate. When posting on a publicly viewed forum, you should expect good and bad responses. As long as the owner likes it, that person should just read the responses and go drive the car s/he enjoys. These are just words anyway. ;)
It all comes down to tastes and what you are used to. Forget 22s, some people are already not liking 18s. That is just their taste. Nothing wrong with it.
From all the pics I've seen, I just can't get used to anything over 20s. I went from 16s to 18s to 20s. With 20s, if the face is a forward design with no lips, I think it is too big too. But when the face is recessed behind some lips, it looks perfect to me, and I stress to me. :)
There is an aesthetic balance and I think 19s and 20s work well with the body of the GS. For others, the numbers are different. We can just all agree to disagree and enjoy our own cars. :D
