Not sure if anybody created this thread yet, but I thought it would be fun.
I personally started watching a few days after Hell-O premiered, but I didn't start watching regularly until the beginning of season 2.
I remember seeing the promos for this show back in early 2009 and half-considering watching it, but deciding not to because of new FOX shows being a let-down in the past. When the show started to hit its popularity in mid-late 2009, it was all the kids at my school were talking about. I thought "Well, it's just another overhyped teen show," because it was mostly discussed by freshmen and sophomores (I was a senior at the time.) Then around Christmas that year, I heard their cover of Don't Stop Believein' on my dad's sattelite radio and thought "Hey, this Glee stuff is pretty good." You see, I was unaware that the show had musical numbers, so once I heard it was a musical (of which I am a fan), I thought "Maybe I will give it a shot."
Then in April 2010, I decided to check out this "Glee" thing after all. I went on Hulu and watched Hell-O and I was amazed by what I had been missing. It was one of the most well-written TV shows I had ever seen in my life and I was hooked ever since. I started watching the premieresat the beginning of season 2 and haven't missed one since. I'll admit it isn't as good at it was in the first season, but it still has a way of introducing well-written storylines and gripping social commentary. I wish this show a good stay at FOX.
So, when did you start watching? You don't have to introduce a long story like I did if you don't want to.
