  We examine the validity of the generalized factorization method and calculate
the angular correlations in the charmful three-body baryonic decays of $\bar
B^0\to \Lambda \bar p D^{(*)+}$. With the timelike baryonic form factors newly
extracted from the measured baryonic $B$ decays, we obtain ${\cal B}(\bar
B^0\to \Lambda \bar p D^+,\Lambda \bar p D^{*+})=(1.85\pm 0.30,2.75\pm
0.24)\times 10^{-5}$ to agree with the recent data from the BELLE
Collaboration, which demonstrates that the theoretical approach based on the
factorization still works well. For the angular distribution asymmetries, we
find ${\cal A}_{\theta}(\bar B^0\to \Lambda \bar p D^+,\Lambda\bar p
D^{*+})=(-0.030\pm 0.002\,,+0.150\pm 0.000)$, which are consistent with the
current measurements. Moreover, we predict that ${\cal A}_\theta(\bar B^0\to
p\bar p D^{0},p\bar p D^{*0})=+0.04\pm 0.01$. Future precise explorations of
these angular correlations at BELLE and LHCb as well as super-BELLE are
important to justify the present factorization approach in the charmful
three-body baryonic decays.
