I do agree that the Grieg is very overrated, even though there have probably been many very fine performances. It's a concerto that pushes the listener's buttons by juxtaposing typical Romantic "emotional" elements and comes out rather shallow. Moulded more intelligently and carefully, the good moments of the Grieg could have formed the basis for a wonderful concerto, but the way they are used is awkward more often than not. Witness, for example, the pathetically simple transitions between the contrasting themes in the finale, which essentially derive the entire movement of any development.
For example, I once heard someone liken the opening octave fall on the piano to a waterfall in a Norwegian fjord. That is not true. It's just an octave fall, meant to capture the listener's attention without adding anything to the music, as in "look, my concerto is cool too, I can write serious piano music."
