By contrast, Ace in Casino reflects on his time in vegas as an old man, still getting work, with a good house and a family, and in the end pretty grateful for everything he has left as the film fades out, slow classical music sending him off as he remarks 'Why ruin a good thing?'. I think the endings to both films are a perfect contrast: At the end of Goodfellas, Henry gets out of everything pretty unscathed with his family, even after ratting out all his friends - and after all that, he has the audacity to bitch about shit as inconsequential as spaghetti, and he's rather appropriately sent off into the credits by a grating whiny cover of 'My Way', which captures his total inability to grow or change or move on, and his pathetic nature by the end of the story.
Casino and Goodfellas are such good companion pieces.
