My ratings of Lost episodes 12-18:
1x12: Whatever the Case May Be = B
1x13: Hearts and Minds = B+
1x14: Special = A
1x15: Homecoming = B-
1x16: Outlaws = A
1x17: ...In Translation = B
1x18: Numbers = D
The way some of the characters (especially Kate and Charlie) get the weird "I'm about to have a flashback" face right before a flashback starts cracks me up. Once again, Charlie's backstory was boring. "Numbers" was the worst episode so far. Horribly written.
