I think this pilot is perfect.You get a sense of what every character is like, and you want to know them more.
I remember when I saw this for the first time years ago, I really wanted to be them, especially Meredith. Their lives looks so interesting.
Also, the music in this episode is fantastic. When they use these song later on in the show, I get chills.
Ellen Pompeo is so good at acting without saying or doing much, just her energy.
