What parts of LOST have made you cry? Or felt most emotional? C'mon admit it, you must have choked up at least once.
My top choice needs to be in 'Deus Ex Machina', where Locke is crying as he's driving in his car after being conned by his father- followed by the on-island scene of him pounding despairingly on the hatch- "SO WHY DID YOU DO THIS... TO MEEE??" I was bawling every time. Giacchino's beautiful score must have something to do with it ('Locke'd out Again' on the S1 Soundtrack.)
What's yours? Could be sad, happy, bittersweet... any strongly emotive moment.
