Everyone has not done the market research already. Take it from me, a person who does this stuff for a living and just a few weeks ago had to review 300 pitches, many of them from experienced and even award-winning TV writers; the average person who decides to pitch a series has absolutely no idea what is popular or what the trends are. This is true in both comics and TV. The vast majority of people will either pitch whatever is at the top of their head at the time, copy something else that's currently popular, or make something that's similar to stuff they liked when they were younger.
Do you know how long market research usually takes? Like a week or two. Even at my day job on series outside my favoured media and far from my personal watching or reading habits, it's literally just look up the latest reports on "Kids media trends" look up what the top performing series in a medium are (like...literally look at the charts on Amazon and stuff), pick out some that are close to what I want to make and have a little look at them or read reviews.
"I don't have time" simply isn't a good excuse when making a successful series means treating it like it's your job.
If you want to be in comics, you need to be interested in comics. And any other medium, this holds true. You need to eat, sleep and beathe that medium. I read other people's comics, I support comics kickstarters and attend comics events, I go to talks about comics, I watch youtube videos about comics, my bookshelves are stuffed with graphic novels, small press comics, and books about making comics, the history of comics, drawing and writing, most of my friends are people who make comics! I met my partner because they made comics and our first date was at a comics event, and we're going to that same comics event this year for our tenth anniversary! The "Market Research" basically dovetails easily into my daily life because nothing about "go read some good comics and find ones I enjoy" feels like a chore to me.
If going and finding stuff to watch or read is a chore, and you keep coming up with excuses to not draw things, you cannot do this job. I'm sorry, that's a harsh truth, but an important one. Comics are bloody hard work, and you will never be a comic artist if you're only in love with the idea of being somebody with a universally beloved comic, but don't love the process of making comics so much that you'd do it even if everyone thought you were a loser and you had just a small band of dedicated readers.
I'm not an animator specifically because even as an eighteen year old I realised that I was in love with the idea of being Nick Park, but I don't enjoy actually making animation enough that I'd slave away at it as an unknown on commercials and stuff. I enjoy making comics though, and I've been making comics since back when I only had literally like five readers just because I love making them.
All this stuff about getting cancelled is... I dunno, it always just feels like excuses. As far as I'm concerned, Pewdiepie has not apologised enough for all the awful stuff he did really not that long ago at all, while plenty old enough to know better, but he STILL HAS MILLIONS. He is still one of the most popular entertainers in the world and he still earns millions of dollars a year! HOW exactly has this "cancellation" affected him!? J K Rowling has had to be overtly transphobic and make a transphobic book AND write some movies that bombed for some people to start to distance themselves from her, and she is still one of the richest people in the bloody world! She could write literally anything and somebody would publish it, and all people would be able to do would be to complain, and then she could go and pout about it a bit and get millions of people saying "ignore teh haterz, we think you are a queen!" Like... the cancellation really doesn't do much, even for these people who openly spout actually damaging ideologies. These people have literally done stuff that encourages hate towards marginalised people and continued to do it even after they were told not to. Even if you got the same response for vaguely saying "looking after the environment you live in is good", or making a comic about cartoon animals (which you won't)... all evidence suggests that absolutely nothing will happen to you and it might even be good publicity.
If something is really, genuinely worth doing, it's worth putting up with a little hardship for. So some people are gonna call you a furry?... I'm a bloody openly lesbian creator! I've been called actual slurs! My work is illegal in some countries, there's an entire movement called "ComicsGate" that tries to keep women like me out of the comics industry by pressuring publishers, but I've carved myself a little niche in comics by dint of extreme effort.... and you're using "some people might call me a furry " as an excuse to not make stuff? That's actually a little insulting to me if I'm quite honest! Making comics is HARD and you are going to get criticised and there are going to be people who don't like your work and people who laugh at you. If you truly care about what you want to make, you shouldn't let anyone stop you.
That's really all there is left. You either need to knuckle down and just friggin' DO IT and weather everything the world throws at you through passion and determination, or if you don't actually have the passion for researching comics, immersing yourself in comics, spending hours reading and drawing them, you need to acknowledge that you're just in love with an impossible fantasy of being a successful and universally beloved creator whose work is above all criticism and... I don't know, do something other than comics.
