Little House on the Prairie... When they started adopting all those kids. I actually liked the Albert character and the actor who played him was very talented, but couldn't they have made him a cousin or a neighbor and not the adopted brother? And then came all those other adopted kids... Degrassi: The Next Generation... It started when they killed off JT and brought in all those Lakehurst kids. Then the storylines became even more unrealistic as the characters started becoming supermodels and pop stars. Degrassi was supposed to be a show about typical Canadian teens. I don't watch it anymore, but the last time I tuned in it was very over-the-top with soap opera-ish plots. I'm starting to get tired of Glee, but I don't think they "jumped the shark" as much as they've run out of ideas. They don't know what to do with the old kids, they don't know what to do with the new kids, they don't know what to do with the teachers.
