Season 3!!
I hate Lauren but I love the relationships between Lauren/Vaughn/Sydney! It's so dramatic, very interesting to watch. And I remember I was always hoping that Vaughn would say to Lauren "I don't want you anymore now Sydney's back"!! The first episodes were heartbreaking! But it's much more interesting than season 5, I didn't like Tom and Rachel, and Vaughn "being killed" wasn't the best thing that happened...
I totally agree with you ! The story line was a lot more interesting in S3 !
I didn't even watch all the episodes of S5...
