She can be boring at times, but she is the main character of my favorite show, so I have to love her. I hated Derek and I believe Meredith turned into a better character after his death, but she still has had a lot of great moments throughout the entire series. Her friendship with Cristina is the best tv friendship of all time. Meredith is great and the show would not be the same without her, but she is definitely not the star of the show.
Honestly this is my favorite Meredith moment, she can be savage at times. Queen of stealing Zola.
the top 3 must be
1. Addison Montgomery
2. Katherine Mayfair
3. The Commander
