Powerful scene:
(and more people VOTE please!

)
This is the one scene that has stuck with me over the years more than any other on the show. Everything about that scene, from the way it was shot (the color coordination between the sky, city skyline, and even the clothes the characters are wearing is awe inspiring), to the music they chose, to the dialogue they wrote and the the way it was acted, was perfection. Tbh, I wish Shameless had more scenes like this, but I understand that the show has different, typically lighter/more comedic aims in mind, and also that this scene was made all the more powerful by the fact that the show rarely takes itself seriously, lending a jolt of shock and sense of credibility towards the rare moments when it does.
What most impresses me about the show is that after 7-8 seasons, it has continued to evolve the characters in such a manner as to never feel stale. Even the Sopranos felt stale after 6-7 seasons, but because the characters in Shameless continue to grow/change/evolve in such substantial yet unforced and natural fashion, the narrative remains fresh and compelling.
Also, I can't help but notice the parallel between Frank/Phillip and Fyodor/Ivan Karamazov from Dostoyevsky's The Brother's Karamazov. Fyodor is the drunken shitbag of a father, while Ivan is the prodigious son with extremely high intelligence who appears destined to climb far above his station and away from his family drama. That is, until Fyodor confides in Ivan that "of all my sons, you are the most like me." It's there we come to the revelation that Fyodor, who prior to this moment had only appeared a mean, short-sighted, despicable and largely amoral drunk, was once a young prodigy himself, with his intelligence now hidden away behind decades of bitterness and alcoholism. And that Ivan, who possesses nearly all of the traits of his young father, both good and bad, is likely headed down the same path. The similarities between the two father-son relationships, and between the two sets of characters themselves, are so strong that the Frank/Phillip dynamic simply
has to have been inspired by and directly derived from that of Fyodor/Ivan.
Just a little classical literary analysis I thought I would throw in there.
