well as far as i'm concerned i liked:
in gf1 there wasn't a prticular favourite scene
in gf2 i liked the scene where michael hits kay , i like it when he just stares at her and as he starts to get mad and unleashing his anger with a slap.
in gf3 i liked the scene where michael was announcing vincent as the new don and as michael was leaving the room he gives a final glance to vincent getting his hand kissed , i juss loved the way michael looked at him.

and that's all i've got to say about that.
