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.
Broken Base: This film has a lot of fans in addition to the Hatedom, many among the furries but also a large number of wolf fans.
A Howl-iday Adventure is this among the fanbase, as it's either seen as a good followup with a decent plot, or a case of Sequelitis with worse animation. The Great Wolf Games is even worse off in that regard.
Cliché Storm: Entire movie in a nutshell: Male falls in love with female. Male realizes he can't be with female because their love is forbidden due to them being different. Male and female get captured, wake up in a new location, and have to find their way home. Then throw in a bunch of kiddie humor during their adventure. Male and female finally arrive home, but the female dies. Oh wait, she didn't actually die. Male and female, despite their differences, fall in love, and live Happily Ever After. The end.AND there's a direct-to-video sequel where they have 3 children.
Cult Classic: When it was first released, it was hugely hated by critics and animation fans alike for poor animation, unoriginal plot, and lame jokes. Jump ahead a couple years, and it has quite a fanbase.
Ensemble Darkhorse: There are a few, as the characters are often considered a (if not the) redeeming aspect of the film.
Garth also gets love for his character development, as well as his bird-dropping howl gag.
Lilly and Garth are also sometimes preferred over Kate and Humphrey, due to their development and dynamic as a couple (see They Wasted a Perfectly Good Plot), to where some fans worry they may disappear because of the franchise's shifted focus on Kate and Humphrey's family.
Moral Event Horizon: King crosses this when he has Runt abducted to draw out the packs' Alphas and makes its very clear that he intends to kill Runt when he's no longer useful.
The head wolf of Daria's pack crosses this when he attempts to murder Daria as a pup due to perceiving her as useless because of her blindness. It gets worse when he murders her mother for defending Daria, because it went against "pack rules". And then he tries to kill Daria again when she returns years later.
Narm: Nars in The Great Wolf Games is meant to come off as intimidating, and does to a minor extent due to his abuse of Fleet. But a lot of the effect is undercut by how he constantly sounds like he has a giant spit wad in his mouth.
Narm Charm: Other moments in the series have this sort of charm, such as when Humphrey and Kate embrace while spinning in the air...only to then flip out. The corniness is just too much to not like.
The Scrappy: Despite being major characters who give directions to the main characters so they could return home, Marcel and Paddy are not really that popular with the fandom. Go ahead and check out any fanbase on Deviantart or Youtube, you'll be surprised that those two have barely to any mention with the rest of the characters, a majority being wolf fans.
Surprisingly Improved Sequel: Alpha and Omega 2: A Howl-iday Adventure has received better reviews than the first movie (such as the sequel's average of 7.0 rating on IMDb compared to the first movie's 5.0), as the plot and humor have improved. However, reviewers still noted its shorter length, lesser animation quality, and crammed holiday elements as issues.
Alpha and Omega: The Legend of the Saw Tooth Cave is considered to be the best of the sequels, thus far. Its plot is far more smoothened out and with less filler, and its animation has significantly improved (especially in comparison to The Great Wolf Games).
They Just Didn't Care: There are some pretty glaring animation issues in The Great Wolf Games, such as Kate briefly turning dark brown and the sky suddenly flickering to a dark blue color as Nars and Humphrey talk. Not to mention the awkward use of the "children cheering" stock sound effect.
Some also feel Lilly and Garth's relationship was more interesting than Humphrey and Kate's, and should have been fleshed out more, if not made the focus, instead. Given how Lilly was The Woobie trying to help ease tensions between the two packs, and Garth was gradually shown to be more than the Jerk Jock he initially appeared to be, along with how they help one another, there is some weight to this.
A Howl-iday Adventure had a pretty good plot concerning Runt's abduction by the Rogues, his bonding with Princess, and everyone's effort to find/save Runt. But it is undercut to a degree by the short running time, crammed-in (and unnecessary) holiday elements, and, depending on how you look at it, how the Rogues are ultimately defeated by bears rather than just the wolves themselves. All of which could have instead been spent further developing the plot.
The Great Wolf Games features Nars being bitter over Kate beating him in their own Wolf Games and trying to push his son to be the next champion. It would have been interesting to see Kate handle a competition against a rival who hates her guts while she's since moved on. However, Kate's barely even in the film, and Humphrey takes the role of coach, instead.
There were rumors that King would attempt to seek revenge, and Princess would seek to redeem herself in The Great Wolf Games. Needless to say, neither plot occurred, much to the disappointment of quite a few fans.
Ugly Cute: There's Salty, Humphrey's friend who resembles Scrat. Also, Legend shows Tony when he was a cub, looking like a tinier version of himself, and with a noticeably flatter face.
Uncanny Valley: The wolves have somewhat human-looking facial features, which can be quit disturbing sometimes. The Anime Hair doesn't help either.
The cubs of the sequel Alpha and Omega 2: A Howl-iday Adventure also have this issue, even just looking at the cover art, due to their human-like features and big eyes. Runt gets it the worst due to his smaller size with the big eyes.
Unfortunate Implications: As this reviewer pointed out, the whole 'Alpha and Omega' ranking is only determined by the colour of the fur, nothing else. Another thing he points out is that during the climax, while Kate takes only one blow before her Disney Death, Humphrey takes plenty more blows shielding her from the caribou, making her into a Faux Action Girl.
The Woobie: Again, Lilly in the first movie. She's a Shrinking Violet who's not as skilled as her older sister, trying to keep some degree of peace between the two packs, and in love with a guy pack laws forbid her to be romantically involved with (especially after the two bonded while helping each other, noticeably getting Lilly to come out of her shell). This is perhaps best demonstrated in the scene where she's visibly depressed as she helps Kate get ready for the arranged marriage.
Humphrey is also this in the first movie for similar reasons, although to a lesser degree. Still, there's the moments like when he's about to confess to Kate that he loves her...only to see she's run off to stop the packs from warring.
There's also Runt in the second movie, given how he's disrespected by his siblings and then abducted by a villainous group of wolves to be used as bait in their scheme, with the constant threat of death.
Daria of The Legend of Saw Tooth Cave is a she-wolf who was forcibly made into an outcast when she was a pup because of her blindness. Even worse, the head wolf of said pack outright tried to murder her because he perceived her as a burden, and killed her mother for getting Daria out of harm's way. By the conclusion of the film, she just wants to hear her mother's voice again.
