These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Ginga Densetsu Weed
Tropes used in the animated adaptation:
Adaptation Displacement: The show seems to receive more recognition and attention than its predecessor, mainly for the "old school" animation the latter has which may be seen as an acquired taste these days (which is ironic when the motions and looks of the dogs in GNG are usually better animated than GDW). That, or they simply don't know of it.
Alternative Character Interpretation: A good lot of this over Weed. Is he a naive, yet still effective leader whose morals are needed in the kind of world he lives in, or is he really just a textbook example of Good Is Dumb who wouldn't have lasted five minutes had he faced Akakabuto with the same kind of mindset?
Angst? What Angst?: Weed spends about a minute mourning his mother's death before getting super excited about going on a journey to find his father.
Anvilicious: Oh boy... don't get started on Weed and his morals...
Ass Pull: Some find Hougen's death by lightning to be this.
Base Breaker: Good Lord, Weed. There are those who see him as a na´ve brat who forgives his enemies way too easily and mostly rides on his father's coattails, and then there are those who think that he actually has a point with his morals and is, overall, a fine character even if he didn't happen to be the son of Japan's most famous dog. In short, one should be very careful when voicing their opinion over him.
Complete Monster: Hougen is possibly the most evil and malicious dog ever portrayed in any media or at least a strong contender for the place. He introduces himself to the legendary heroes of Ohu by taking a shit and telling them that if they eat it, he'll let them go. He then paralyzes the heroes by threatening to kill a young female, Reika, if they dare to fight back. He has the heroes beaten almost to death as a result. Hougen frequently laughs at pain and desperate acts of heroism and defiles the corpses of those he's defeated; in one snowy scene, he sits on a recently dead dog to keep warm and jeers at the fallen's companion that he'll sit on him next when he dies. Hougen is not above using his lackeys as expendable shields, sending dozens of them to their deaths against opponents whom he can beat himself. When he has temper tantrums, he brutally kills whoever happens to be standing around. Hougen is also a serial rapist, who demands his underlings to round up females for him. He forces Nero (then-pack leader of one of the main characters, Lovable Coward GB, and a minor villain) to kill the abandoned puppies right in front of GB (GB was about to look after them but brought them at the wrong time) just to prove that the puppies weren't Nero's - and that Nero, therefore, isn't hiding a female from him. This, by the way, doesn't save Nero's hide in the end. Later (chronologically) Nero encountered the leaders of Ohu and is swiftly cowed into submission by them trying to justify his cowardice to Hougen by saying that they threatened to bite off his legs and piss on his face. Hougen immediately makes an example out of him by doing exactly that. Even finding out that Hougen and his brother were trapped by their human owner for so long that they had to resort to cannibalizing the dogs trapped with them does nothing to evoke sympathy for his cruelty. The only smidgen of honor Hougen shows throughout the whole series involves a pact he and his brother made, that if Genba dies, he wanted it to be by Hougen's fangs. When Genba suffers a head wound that drives him psychotic, Hougen kills him. Then promptly turns on the dogs who were with his brother, tears out their throats and hurls them from the top of Gajou.
Damsel Scrappy: Many fans dislike Reika for her role of "Just There" in the anime/manga and getting kidnapped.
However, Reika does have some redeeming qualities and manages to get some slack from the fans because of that. The same cannot, however, be said about Koyuki, Weed's mate who only appears in the manga and seems to serve no other purpose than to give birth to Weed's puppies. Unlike Reika, Koyuki is pretty universally hated by the fandom.
Early on, the dogs make a deal out of how they'll be recruiting young dogs for a new generation of Ohu soldiers, because the previous ones have gotten old (or are captured). However, Ken and Tesshin were puppies back in GNG, meaning they're at least 10 years old, no more than two years or so younger than Gin, which is basically the equivalent of an old man in dog years. Kagetora as well is shown to be best friends with Ken and having known him for a long time (more clearly pointed out in the manga), implying they're roughly the same age.
Hilarious in Hindsight: When the dogs first meet Hougen, he takes a dump and tells them he will let him go if they eat it. They get offended and disgusted, as you would expect, until you realize dogs in real life will readily eat poop.
Howling dogs in the sad scenes, such as John's death, sound more like humans screaming or coyotes barking instead of the true dog howls. It seems that the animators, writers and voice actors of the anime just didn't care.
Likewise, the strange trumpet melody playing during John's last moments feels a bit unfitting, more like it's a melody trying really bad to sound sad, and failing.
Just one of many moments ruined by terrible animation: Tokimune's death at Kaibutsu's jaws. No, not the actual death - a shot of Weed screaming "Father!" looks like he's having a friendly conversation.
Narm Charm: Despite having ridiculous amounts of Narm, some people still find the anime watchable, even enjoyable.
It depends what episode you're watching, really. There are a few well animated ones.
Replacement Scrappy: Jerome's helpers were hated by most fans for replacing the manga characters who were cut out from the anime. Though Ryo did have fans for being an Action Girl (which is rare in this series).
Ending Fatigue: One of the major complaints among the fans who read the manga especially for the later arcs.
Ensemble Darkhorse: George is one of the favourite characters among the manga readers. He isn't in the anime. This is just another thing that made the fans unhappy.
Tesshin is also an example of this. Apparently he's very popular with Japanese readers.
Unfortunate Implications: Near the end of the manga, many fans were unhappy at the idea of Weed and Koyuki mating and having puppies. Even though they are dogs, it has an unpleasant parallel to the implications of teenage pregnancy as both Weed and Koyuki are too young to become parents.
