I saw Sopranos the third part (first season) of the Sopranos and in the end I saw some resemblance with the GF.

When Tony Soprano is looking to his daughter(singing) you see switches between that view and that of the killing of ??? and almost killing of ??? by uncle junior. Also Michael is sitting in the church (that's something religous) and Tony is watching people singing a religous song. This is almost the same as in the GF. Except that Tony didn't order the killings.
