Unpopular Kirby opinions:
-Kirby Superstar is overrated; The only part that I really enjoyed of it is the Dynablade chapter but it's too short, and the great cave offensive is annoying, especially the underground tower (though I love Amazing Mirror, because I think it improved the metroidvania concept in the right way).
-I prefer Kirby's spin-offs more than the main games; I love how creative some gameplay ideas are in those games, while I think the main games are a bit stale and the same every time (this does not apply to every game, is a general thought, there are special cases like Triple Deluxe, that's awesomely made and it's impossible for me to not love it).
-I don't like having a recurring villain. I love Dark Matters to death, but I don't want them to return (well, maybe as cameos or reference, but not as characters).
-I don't like Marx, I like Magolor even less, because he is a Marx rip-off and I don't like rip-off characters; Also, I think Magolor is one of the most bland character of Kirby's history (his bossfight was bland, not epic at all, and his personality is complete nonsense) and it bothers me when the developers insist putting him as a cameo everywhere.
-I kinda hate when people think that every red thing in Kirby is blood. When I played the Zero battle for the first time, I never thought that it was blood; Zero is a cloud of darkness, and he uses that red thing to attack you before exploding. I think it's just red-colored matter, and being a cloud, it doesn't have any blood; he's not even solid. Dark Metaknight's "blood" is ridicolous, I didn't even noticed it before reading about that on Internet.
-I think Zero and Zero2 are influenced by an Evangelion movie (it's very disturbing, I suggest to not search about it unless you're aware of what you're searching for). The red thing was LCL in the anime, I think the color scheme of Zero is a reference to that (kinda like Super Sonic is a referencce to Dragonball Z).
-I hate super abilities and hypernova. They are boring to use and forced. When I reach the hypernova part of a level I usually pause and quit.
-Kirby's Dreamland 3 is the best Kirby game, and it's a piece of art.
-Visually, I prefer Kirby without ability hat. Now the ability hat are very integrated to the series and I don't pretend them to be removed (I also think that some hats are cool), but I prefered when Kirby had no hats, because It makes it feel like if Kirby has that ability because he has that hat on his head, not because he copied it from the enemy... it's hard to explain, but makes me think that the power comes from the hat and not from Kirby (kinda like Mario's power come from the power ups he collects during his adventures, and not by himself). Also, I feel like the hats are limiting Kirby's possibilities to transform himself... basically he transforms himself only with the rock and wheel ability, while in the games with no hats, he can transform himself a lot more.
-For a character, relevance to the plot or being playable doesn't make it important. To be important, a character has to influence the subsequent games, even if it doesn't come back directly. Because of this, I think that characters like Drawcia are very important, since lots of elements in the modern games are inspired by her and her game; on the other hand, characters like Gooey are completely irrelevant since it hasn't influenced the series in any way.
-and well, I'm sorry to say it in the Bandana Dee support thread, but I can't hide it, I don't like Bandana Dee and I think that he's taking the spot of other characters. (I disagree with the argument that's generic, but I dislike it anyway because I think that as a character he's unoriginal and doesn't add much to Kirby's universe); I'm fine with him appearing in games, as long as he remains a Dedede minion and not a main character.
