I think it improves the rear of the E90..... not that there is anything wrong with the rear without a spoiler IMO.
From the pictures I thought it was not such a big deal, but after seeing it in a real car last weekend, I was very impressed.
I saw it on a Silver E90 during the day, and on a Black E90 at night... it's elegant and not overdone.... I would say go and check it on a real car before making a final decision on it.
