All I know is my hype died after Magical Mystery Cure.
I just didn't get interested in Twilight's journey as a princess. I got to watch most of Season 4, but I felt like there was nothing more for her to accomplish. It's like being a princess is wow, the biggest accomplishment she could get. No more reason for watching. Maybe Lauren was right, maybe the series finale should be Twi becoming a princess. Not the end of Season 3.
