A typical non-categorizable simpsons-episode about parenthood and the elderly influence on offsprings friendships, about protection of children of their own, our archaic roots and present day survival of the fittest themes in societal life. I liked the many references this episode had, especially one line: "breath in the expensive candle and exhale the tension" from lisa to her mom is one of the gentle moments about the ridicule of our accessories we don't need most of the time. Not to forget, the stylized ancient voiceless pictures are worth to watch this anyway. Present day and archaic cutbacks are presented in an allegorical pace, awesomely interwoven into a story where parents lack of being able to shift perspectives is one central element of the cinematography. A must watch for simpsons-fans!
