Episodic writer Krista Vernoff provides some of the best, most witty dialogue in this week’s installment of Shameless. If I have one complaint about “I’m the Liver,” it’s the pacing. The episode switches from scene to scene, story line to story line so quickly, you barely have time to digest what you’ve just seen before another story line pops up. I mean, some scenes contain only one or two lines of dialogue! Other than that, “I’m the Liver” is an extremely entertaining episode.
