Season 5. Or 2. Or 3. Or 4. Or 1. I like them all haha.

I liked all but S4. I do believe that the current season is going to be my favorite though!

i LOVE S2 and S3 the most. i also love S1 and S5... and S4 too LOL and i think S6 is gonna be AMAZING :)

merder are together for the whole thing

Season 2 definitely. It had more depth, IMHO.

But I'm loving more season 6 than I've loved season 5 :P

I can't really choose! Love everything but s4

Defo; Had My Favoruite Couples In It; Amazing Storylines It Had Everythink For Me

Definitely Season... MerDer happiness and I thought it had some AMAZING storylines.

Season 5 with the whole Derek and Meredith engagement followed by the post-it wedding even the whole Anatomy Jane episode where Richard tells Derek, "Except for your girlfriend. She used to carry that thing around when she was five years old. It was cuter in a child."

Because of Cristina and Owen ♥
I stopped watching while Season 3, then friends told me about them and they got me watching again and now I love Grey's more than ever because of them :]

s2, s5, s3, s1 and s4 was okay. but 2 and 5 are mi faves and im loving s6 so far.

I started watcing the sow when season two was on tv, and back then it was my absolute favorite tv show! So that's why i have to say season 2.

Ohh but I agree with livexthexlife92. Season 5 is close after s2 and I also love season 6 :)
