Alright. With more than half way finished, and with the recent receipt of the Peabody Award, Season 5 is looking to be the fan-favorite season of the series. Of course, it will have to compete with season 1, which won the Emmy; even Season 4, which was nominated, could possibly stand in the forefront of fan's minds. However, there never seems to be any dispute about what the worst seasons were: # 2 and 3.
Granted, the hatred for Season 2 is understandable; it started out well with Desmond, but then dropped his story and got as tiresome as the pushing of the Button. It also introduced Ana Lucia, my least favorite character of the series, and Libby, the most-backstory-that-matters-but-doesn't character of LOST. I do think, though, that Season 3 is short-changed quite often. (I know... Nikki and Paulo...)
After rewatching some of the episodes on abc.go.com (great website for those who want to revisit the past four seasons for free), I've realized that, at least in terms of Ben-and-Locke dialogue, it doesn't get much better. I strongly recommend watching "The Man From Tallahassee," "The Brig," and "The Man Behind the Curtain" back-to-back; watching the dynamic of the two of them battling for power is extremely intriguing, and shows Terry O'Quinn at his absolute best as John Locke.
Some of the best lines from those three episodes:
LOCKE: I can't... ORDERLY: Mr. Locke, you fell out of an eight-story window and survived. I don't want to hear about what you can't do.
BEN: I'm sorry. He's not who we thought he was!
BEN: I've lived here all my life, you've been here 80 days. What makes you think you know more about this Island that I do? LOCKE: Because you're in the wheelchair, and I'm not.
BEN: Jacob is not a man you visit. He's a man who summons you. LOCKE: Well, there's a first time for everything.
I encourage everyone who reads this to revisit at least those three episodes. That's when the dialogue popped off the page, which I feel it rarely does nowadays.
