There were many emotional scenes for me, but for some reason at the end of gf 3 (michael passing away with no one)i get so emotional.

However two other scenes that got to me were the end of gf 2 (the flashback scene) this makes me feel bad, seeing all the family together alive, it especially makes me feel bad when Fredo congrats michael and then is told off by santino, this gets to me because we just witnessed the death of fredo.

And lastly in gf 3 when michael confesses his sins, and they way he presents his sin of killing his brother saying, my fathers son, mothers son etc.

but yea, most emotional definitely end of p. 3
