A surprising fact that had been noticed before its inconsistency with the AdS/CFT was realized is that the stress-tensor can change sign and, in particular, vanishes for θ θ = π π / 4 . This would imply that the corresponding correlation function in the Chern-Simons matter theories vanishes, ⟨ ⟨ T a b j 0 j 0 ⟩ ⟩ = 0 , which is not the case.
