Fringe was about their budget being slashed. Gilmore Girls was about the producer walking. And Atlantis got more perfect every year.
No. Just no.
Fringe was great for three seasons, the 4th season I remember ditching, and the 5t seasons didn't address and issues that actually needed to be, so there is no conclusion to "Why?"
Gilmore Girls became bad overnight in season 5 with the Rory and Dean BS, then Logan, and became almost unwatchable in season 6 with the Luke storyline. All of this before the creator walked with the biggest "FU" ending in season 6.
Atlantis got worse every year with the show not having a clue what they were doing, killing off characters left and right for no reason, then bringing then back randomly. Replicators? Evil Asgard? Girl Teal'c being pregnant and that horrid storyline. None of that was needed. Making Sam take command of Atlantis even tough Amanda Tapping wanted to leave. I almost made a topic about how bad the choices for that show were.
