Hi there dudes, here's a little tip: IMDb, the world's biggest database of movie and tv series, has its own charts. A series must have at least 1000 votes to be included in that charts, but Lost has 950 votes to date.
So, my tip is: sign up to IMDb and then vote on the Lost page (you can also rate every single episode, if you want, but now I'm talking about the Series overall), at this address: http://www.imdb.com/title/tt0411008/
You can stay in touch with the charts on the genre pages of the site (ex. "Drama" chart has The Wire as number 1 http://www.imdb.com/search/title?genres=drama&title_type=tv_series&num_votes=1000,&sort=user_rating,desc)
Thank you, namaste and good ratings.
