On the one hand, that Spy School show sounds really cool. On the other hand, you butterflied the Teen Titans cartoon away, and I really liked that series. I'm not sure how to feel about this...
Yep, as already mentioned, we've got a live-action
Teen Titans coming! I was bummed at no cartoon
Teen Titans too (it was one of my favorite shows back in the day) but I'd have probably gotten really into
Spy School (and Sara would be my waifu

)
Intresting series. I guess Elliot gets a lot of Draco in Leather Pants, right?
Not so much. Perhaps a bit early on, though it's less so once he goes completely off the deep end. He does have some justifiable motivations (and he is good looking, so he also has a decent amount of female fans), but he doesn't get as much admiration from the fandom as other similar villains on other shows do.
It's a trope/saying. It's when a fandom makes a villain not so villainous or evil because they're hot/cute/etc. So Sephiroth or Draco.
So are Gundams here magic, magitech, or what? I'm a little confused by what they're supposed to be.
Biotech. The progenitor civilization was so advanced that they learned how to attach a Gundam to the human soul, but it was this tampering with the spiritual forces of nature that ultimately led to their downfall.
And I'm guessing Rachel in TTL is more of a polarizing character cuz shipping and viewed almost the same way as fans did Lizzie in OTL KND,
She's VERY polarizing, even though she's largely similar to her OTL KND character and doesn't really give fans much of a reason to hate her aside from being Nigel's girlfriend. As for Lizzie, there is a Lizzie-like character (and voiced by Grey Delisle no less) but her attraction to Nigel is more one-sided and it ends quickly, she ultimately becomes one of Sara's close friends.
