  The present status of the LHC anomalies found in exclusive semileptonic $b\to
s\ell^+\ell^-$ decays is discussed with special emphasis on the exclusive
4-body angular distribution $B \to K^*(\to K\pi)\ell^+\ell^-$. The treatment of
hadronic uncertainties in this mode is briefly reviewed, and some of the
analyses in the literature are critically reassessed. The global picture
provided by the global fit points to a coherent pattern of deviations with a
significance substantially above 4$\sigma$ for different New Physics scenarios.
Finally, we propose as the next step in the field to focus on the study of
optimized observables that compare electron and muon modes, sensitive to
lepton-flavour universality violations and free from hadronic uncertainties
(including charm) in the SM, the so called $Q_i$ observables.
