Both movies are compelling. I guess to think of the word tragic I would have to go with GF3. In GF2 Michael's actions dictated the ending he got their. He might have been meloncholy and regretful, but I don't think him sitting alone in a nice house is what I would consider tragic. Seeing your beloved daughter killed in front of your eyes and dying with nothing around you but a skinny dog I would consider to be more so.
