Degrassi
When I was first introduced to Degrassi, it was through the DVD, Jay & Silent Bob Do Degrassi (which showed a couple episodes late in The Next Generation, Season Four, where Kevin Smith and Jason Mewes made a guest appearance). Back then, I was a somewhat big Kevin Smith fan, and I watched it expecting the humor he's known for... and basically got the polar opposite of that, disappointing me greatly.
Later down the line, however, I developed more of a taste for drama, and after hearing the acclaim Degrassi received for just that, I checked it out, expecting its actual genre that time around, and was hooked. Since then, I'd collected all the seasons of both the original show and The Next Generation.
Digimon
Back when I was in high school, and Pokemon was still a big thing, it was practically required to hate Digimon because it was a "Pokemon ripoff" for also being a monster show and also having "-mon" in the title, and for a while, I gave in, claiming I hated it, and even thinking I hated it at times, despite not knowing much else about it. However, my best friend kept telling me how awesome it was. Finally, I decided to actually check out an episode (the one where Myotismon crossed into the human world), loved it, and aside from the aforementioned similarities to Pokemon, saw that it was a very different, and better, show.
Books
Thanks to ADD, I had very little patience for reading, at least as far as the written word was concerned. More often than not, I would read the words, but not take in any of the story they were conveying. When I was little, my parents tried to get me into reading, and when I was questioned about one of the books I'd tried to read, but failed to understand, I tried to weasel out an explanation, and got a world-class scolding from my dad (granted, he was more angry that I lied). Since then, I hated reading for the longest time.
However, being a video game fan, I eventually got into JRPGs and visual novels, and enjoyed the storylines, which gave me more of a taste for storytelling. Finally, I started working as a school custodian, which allowed me to listen to my MP3 and CD players while I worked. One day, I decided to check out what was offered at a bi-annual school book fair, just for the heck of it. I was tired of listening to the same music again and again, and decided to buy one of the audiobooks (the first Hunger Games book), and loved it. Since then, I'd been borrowing audiobooks from the library like crazy. I still have trouble reading paper-and-word books, though.
Pie
Yeah, this one's a little silly. The first type of pie I'd ever tried was blueberry pie, and while I liked standalone blueberries and blueberry cupcakes, I found blueberry pie to be slimy and gross. I knew there were other kinds of pie, but after my bad experience with blueberry pie, I just didn't want to try any others. Later down the line, my godparents baked the supreme awesomeness that is apple pie (not that I knew it yet), and while I was reluctant to try it, I figured it would be better manners to actually try eating some and say I didn't care for it, but as it turned out...
Anyway, yeah, I love apple pie (ironically, I don't care for standalone apples). I did give blueberry pie another chance, but still didn't care for it, though.
