best us episodes/series i would recommend:

1. One Tree Hill

Of course, I would go for OTH. lab lab. A story of a low profile typical basketball guy named Lucas gets into the varsity team who falls in love with a blonde girl, Peyton, whose life is her art, rock music and cheerleading. Her current boyfriend is the captain ball of the varsity team, Natahn, and is theLucas’ half-brother. Lucas and Nathan never treated each other as brothers. Lucas’ bestfriend Haley is the witty conservative tutor girl in school and later becomes Nathan’s love ineterest. Peyton’s bestfriends Brooke is the bitchy type yet so true bff of Peyton but later also becomes Lucas’ lover. All these characters are in this small town of Tree Hill yet hoops and twists change all their lives.

2. Heroes

A story of a bunch of people from different places around the world who possess different kinds of abilities: ability to read minds, teletransportation, split personality/2 personality, ability to fly, invincibility, ability to predict the future through painting, telekinesis, and a lot more. They are destined to save the cheerleader and save the world.

Main Characters and Their Abilities:

3. Grey’s Anatomy

a Comedy-drama series

Grey’s Anatomy is a hospital drama that focuses on Meredith Grey (Ellen Pompeo), one of several first-year surgical interns, (now first year resident) at a Seattle, Wash., hospital. Along with her colleagues, Meredith struggles to maintain relationships while staying sharp at her new job.

The professional roles and real lives of a diverse group of surgeons collide unexpectedly in this Golden Globe-winning ABC television drama. As an intern at prestigious Seattle Grace Hospital, Meredith Grey (Ellen Pompeo) tries hard to live up to the reputation of her legendary surgeon mother while hiding the fact that her mom now suffers from Alzheimer’s disease. As if life weren’t complicated enough, Meredith also falls for her boss, Derek Shepherd (Patrick Dempsey), a surgical resident recently relocated to Seattle from New York. Meredith’s friend and rival Cristina Yang (Sandra Oh) finds herself in a similarly taboo romance with Preston Burke (Isaiah Washington), Derek’s chief competition for the title of chief resident. As for Meredith and Cristina’s fellow interns — Isobel “Izzie” Stevens (Katherine Heigl), George O’Malley (T.R. Knight), and Alex Karev (Justin Chambers) — they’ve got problems of their own. Izzie doesn’t want to be judged for her underwear-model past; Alex is better at bedding the ladies than bedside manner; and George can’t get any of the women around him to see him as anything but a cuddly friend. All five interns answer to the roar of senior resident Miranda Bailey (Chandra Wilson), affectionately known as “the Nazi.” But even Dr. Bailey jumps to it when Chief of Surgery Richard Webber (James Pickens Jr.) is on the scene.
