Is the Spa-Francorchamps circuit still as special as it used to be?

This coming weekend, the F1 circus will descend on the iconic Spa-Francorchamps circuit. The track is challenging for several reasons. For one, the weather there can quickly turn to rain. In addition, the famous Eau Rouge corner has already claimed several lives. Modifications to make the corner safer mean it can now be driven at full throttle. Do F1 drivers still find the track in Belgium special or does it now lack challenges?
