The following is my opinion on a rather sensitive subject. Readers discretion is advised. If you don't agree with my views, then be polite when you make your response.
Back in the day, the LGBT community wasn't exactly in the best of situations. More often than not, they were on the business end of knuckle sandwiches, among other things. While such behavior is still present, bigotry eventually gave way to acceptance, and I, along with many others, couldn't be happier, as some of my friends growing up were gay, so to see that gay marriage is legal in all fifty US states makes me immensely happy.
In terms of the media, more specifically movies and TV, they seemed more accepting. Gay and lesbian couples began appearing in the media more often, first on more mature shows like Will and Grace, and now, finally, we have them appearing on shows like Steven Universe and, of course, the Legend of Korra. Speaking of which, it is the titular character herself who is not only bisexual, but in a lesbian relationship. Is it any wonder that I find the show interesting? In fact, without Korrasami, I never would've gotten into the Avatar franchise at all.
After watching both shows, I admit that the Last Airbender was much better. For instance, the characters, like Aang, Sokka, Toph, Zuko and Katara, had surprising amounts of character development, and it really made me like them. Zuko's development in particular was especially noteworthy. Another notable thing is that the Last Airbender felt like a continuous story. Yes, there will filler episodes, but this was a good thing, as most of these episodes, barring one exception, were written well and developed the characters more.
The Legend of Korra had this as well, especially with Mako and Bo Lin. Even characters like Varrick and Prince Wu had character development. However, it felt like the effort placed in the Last Airbender was more noticeable, with only the fight scenes being better than in the previous show. I'm not saying that it was bad, however. It just wasn't as good. Also, no filler episodes exist in LOK if I recall correctly, but that's beside the point.
At the end of Legend of Korra, Korrasami fans rejoiced as Korra and Asami became a couple, something that will be touched upon in the newly-announced comics. While I applaud the creators of LOK for making Korrasami's concept (a same-sex relationship in a kids/teens show) a reality, here is when I cringed. Now hold on. Don't go assuming the worst because I don't like a paring that you do. As a concept, Korrasami, while being done before, has managed to be met with a warm reception. The only way this sort more explicit same-sex paring could've been recieved in the past was negatively, hence why most writers, like those who made Batman: the Animated Series, chose to portray those characters, like Detective Montoya's lesbian relationship, with both subtlety and tastefulness.
I have said many times that Korrasami's concept is good and that I praise the creators for implementing it. I do, however, feel that the gay community deserves not to be represented by one-dimensional, borderline-static would-be mary-sues. Korra had great character development throughout the series, making for a lovable character and just the kind of role model someone could ask for. And then there's Asami. Korra and Asami are like orange juice and gatorade. Both taste great, but which is healthier? Korra the Orange Juice or Asami the Gatorade? Korra got all the development. Asami was largely static. Allow me to explain.
As a character, Asami Sato was the technical expert, using wide varieties of gadgets and her own martial arts skills to get Team Avatar out of jams. She first started off as a bland romantic rival for Korra during the first two seasons. She then became Korra's best friend in season three, and then Korra's love interest in season 4. Throughout the series, Asami gets barely any development and any attention that could've been given to her was either wasted on teenage angst with Mako or just completely ignored. There is only one profound thing that truly developed her character: her daddy issues. Truly, Asami's arch-nemesis was her own father, Hiroshi Sato. His betrayal and imprisonment presented the writers with many ways to develop Asami, but nothing truly relevant came of it until season 4, when Asami is forced to work with her father on taking down Kuvira. Once that ordeal was over, there was nothing left to change, as Hiroshi sacrificed himself and the series came to an end. Ultimately, everyone else developed more than Asami did, such as when Korra lost her past selves or when she recovered from her PTSD.
With the LOK comics officially announced, and with Korrasami taking center stage, I expect that Asami gets the development she needs. I will consider myself a Korrasami fan if that happens. Until then, I will say that the LGBT community deserves much better than what they were given. For now, we the people will have to take the good with the bad. We'll have to take the yin with the yang.
Again, I stress that politeness is key, so please respond politely, if I missed anything at all, tell me.
