I had to go with Excellent. Not only was this one one of the fastest hours of Lost but they also tied in some stuff from season 1. Continuity is a big plus. Seeing Lostzilla, the ruins, Christian - just too much good stuff.
I'm a little disappointed that Damon and Carlton broke their rule about Smokey. We know he likes to slam people around and drag people into the "Cerberus Vents." We didn't learn anything new about him. That's the rule.
I wasn't shocked or saddened by Charlotte's death. I really don't understand what the point of her character is or will be. Other than that, great stuff, and one of Lost's finest endings.
I wasn't shocked. But I was saddened. I'm one of the few that liked Charlotte last season. I don't know where her character is going either. But I think she's about as dead as John Locke circa 2007 is. She'll be back. Regularly. But her death scene was really well played. Jeremy Davies almost had me crying.
