plot reboot, meaning there are no Takeru, Hikari, Patamon, Tailmon or anyone else you actually care about to be seen
the first 13 episodes are a complete slog and worse than the World Tour arc of 02 and Hunters combined
the main characters in the first arc are just awful: Takato is a crybaby pussy, Lee is a neurotic worrywart, Ruki constantly has a stick up her ass about everything and is literally a shittier Digimon Kaiser without any of the traits that made the Kaiser enjoyable as a villain
The digimon all have annoying voices, Guilmon is a retard with a bread fetish, Terriermon is recycled from the movie, Renamon is a mindless drone for Ruki while simultaneously being a Mary Sue, Impmon looks like a Sonic OC, Culumon is a toddler
the shit pacing in these first episodes makes it take way longer for the characters to become even remotely likeable so unless you know it'll get better later you will hate every single one of them except maybe Impmon simply because he's fucking with everyone else
the cards make the digimon way too fucking powerful, i.e. guilmon being able to kill icedevimon because "CARD SLASH LOL" and they feel like manipulating your mon via illegitimate means unlike evolution which is natural and established to be a part of digimon on a biological level
the story is unnecessarily dreary and edgy without any rhyme or reason, Adventure struck a perfect balance between funny lighthearted fare and darker serious moments while Tamers has none of that and is literally "Neon Genesis but with kids"
Renamon is literally everywhere on the internet and people keep hailing her as the second coming of Jesus even though her design is ugly and she has no personality
people keep jerking off Tamers constantly and trying to imply that you dislike it in any way will result in you being sent death threats by the fanboys
