I review theoretical progress in the study of semileptonic tree-level B decays and its interplay with recent experimental results. In particular, I focus on two anomalies: the ratios $R(D)$, $R(D^{*})$:
$R(D^{(*)})=\frac{BR(B-> D^{(*)} \tau \bar \nu_\tau)}{BR(B-> D^{(*)} \ell \bar \nu_\ell)}$
and the inclusive vs exclusive determination of $|V_{cb}|$.
I review several explanations for such anomalies and discuss further tests to clarify their origin.
