I thought this article was quite positive about the E92 M3. The writers were just complaining about the fact that everytime they test drive the newest iteration of the M3, the car is progressively farther away from what the M3 was intended to be (their benchmark is the E30 M3 street racer).
BTW, this issue of Automobile also has an article about the upcoming C63. They are really high on this car - looks, handling, suspension, SPEED. They claim that the C63 will be the closest direct competitor to the M3 and may very well be the new king of the hill.
