Sawyer: A con man. He's probably one of the funniest characters on the show. He makes fun of people and gives the people on the island nicknames. He can get really angry at times and can have his sick moments.
Ben: A master manipulator and the leader of the others. The others are a group of people who live on the island and has been living there for quite sometime. He is a liar and is shown to be a villain in the earlier seasons but later becomes a good person. I want to explain more but more characters I'm gonna name.
Daniel Faraday: A physicist. He came in the later season (season 4) A smart guy who knows a lot about space and time travel. He usually finds the solution on a scientific problem.
Kate: A fugitive born to run. She is a compassionate loving girl who does anything to help others. I like her because she's pretty, loving and can be tough at times. She is also clever at times but can get a bit annoying.
Hurley: Won the lottery but thinks he's cursed. He is a fat and jolly guy and like Kate but not as annoying. He finds the easiest solution to a problem and is good at heart. I think he only killed 1 person throughout the entire series.
Fave Season: 4 because although it has the least amount, all episodes are intense or superb and well done, and is sort of the anti-finale of the series. A lot is going on in this season and gets really intense during the final episodes. Season 5 and 6 are similar but lack the beach setting, which I personally like. It gets more complicated at Season 5 and 6. Seasons 1-4 were simple, especially season 1.
