I can't stress enough how much I love this episode. It starts out like our usual Monster of the Week show and it quickly turns in an alternate reality episode that is both incredibly entertaining to watch and undeniably deep and meaningful.
First things first, I have to say that Eric Kripke, at his first directing job, achieved a great result: the direction of "What Is and What Should Never Be" is smooth and sassy, frightening and subtly ominous from time to time, without forgetting a good, occasional humorous injection. Furthermore, being a huge fan of David Lynch, I was beyond pleased to see a clear homage to "Blue Velvet" (the picket fence with yellow and red roses), and even more pleased to see that the same poetic that was conveyed by the movie (the evil lurking beneath the shiny surfaces of the bourgeois, Mid-American lifestyle) was in the episode too, with Dean catching menacing glimpse of the dirt and malevolent forces that toss about under the outward appearance).
The script - the last one wrote by the excellent Raelle Tucker - was incredibly deep and profound and it painfully shows how a normal life could be useless and pointless if you are not with the one you love the most, and Sam and Dean not getting along and being forced by the wish-verse to live different, separate lives was a sad anticipation of their division in "All Hell Breaks Loose". Seeing them reunite in the end was not only touching but also meaningful in terms of the overarching storyline: Dean has Sam's back, and we know this from a long time, but Sam has got Dean's back too and the two of them coming together is really powerful. Plus, the script raises an interesting moral question: what would you do if you can choose between the easy path and the hard one? Supernatural has always been a lay show, and this episode is a secular adaptation of a classical Biblical image, and the Djinn - at least in my opinion - is even a more effective gimmick to pose this question, because his mythical existence is basically a twisted version of what each and everyone of us had hoped for at least once in our lives: a genie able to answer our questions and fulfill our desires. In the end, I must say that Jensen Ackles delivered an outstanding performance throughout the whole episode, and particularly during the grave monologue (a mirror of another monologue Dean will pronounce in front of another dead, in "All Hell Breaks Loose - Part 2").moreless
