In this note we study the properties of linearized gravitational excitations in the new massive gravity theory in asymptotically AdS3 spacetime and find that there is also a critical point for the mass parameter at which massive gravitons become massless as in topological massive gravity in AdS3. However, at this critical point in the new massive gravity the energy of all branches of highest weight gravitons vanish and the central charges also vanish within the Brown-Henneaux boundary conditions. The new massive gravity in asymptotically AdS3 spacetime seems to be trivial at this critical point under the Brown-Henneaux boundary conditions if the Brown-Henneaux boundary conditions can be consistent with this theory. At this point, the boundary conditions of log gravity may be preferred.
