This has to be one of my favorite ever shows. I rewatch it often and it never gets boring. The only other show i do this with is Freaks and Geeks. What makes MSCL so good for me is the angela/jordan/brian triangle. I used to be mad for the angela/jordan couple but through the years ive come around to supporting angela/brian.
Its so well written that you can feel what angela feels. Her ups and downs have made me smile, cry and cringe. Great acting from the great claire danes helps a lot. The second best thing about the show are the rayanne/sharon characters. Complete opposites but they worked so well together i always felt they should have become a couple. To be honest i would have loved the gay plotline in MSCL to have been explored through those two rather than gay best-friend ricky. He was a turn off for me and his journey seemed fake and forced.
