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: The Wolverine
Anti-Climax Boss: The Silver Samurai. Most complaints are about his overhyped feature in the film yet his single fight scene did not last long in the climax. And he's the modern Powered Armor version, to boot.
Some fans were rolling their eyes at the prospect of yet another Wolverine film, while others were more optimistic due to its change in director.note Although the problem doesn't seem to be the director
The decision to bring back Wolverine's bone claws but still have an adamantium body has split fans in two.
Moral Event Horizon: If Mariko's comments are anything to go by, Yashida crosses it by faking his death and working with Viper to further the plot of the film through such means as sending Yakuza goons to kidnap Mariko and forcefully removing Logan's Wolverine powers (at one point, he even goes so far as to cause chaos at his own funeral!).
The Yakuza was sent by Shingen, not Yashida. Yashida sent Harada to look after Mariko, so there was no reason for him to hire the Yakuza. His real Moral Event Horizon, if not trying to steal Wolverine's Healing Factor, was killing Harada, his own grandson.
Logan jumping over the guy on the bullet train, whilst screaming. Try not to laugh.
During the climax, Viper chases after Wolverine and Mariko, and hisses as she does so. Both her run and the hiss look and sound ridiculous.
The Scrappy: Viper, with any semblance of being a Magnificent Bitch taken by Yashida himself, leaving her an enormously bitchy Smug Snake with Fetish Retardant. Didn't help her case when Viper's characterization here gives her snake powers note (she didn't have any in the comics, as she was originally "Evil Black Widow") and her actress was terrible in the part. As a final punch to the gut, she has absolutely nothing to do with her comic book counterpart.
It's quite obvious that the train action scene is filmed in front of a green screen.
The Silver Samurai suit doesn't look as convincing as it should be considering how well rendered armored battle suits in movies like Iron Man are nowadays.
While the digital bear at the beginning of the film is somewhat hokey, the practical-effects created bear that appears shortly afterward just screams animatronic.
Strangled by the Red String: Logan constantly dreams about Jean Grey and wishes to be with her again yet he shares a few intimate moments with Mariko, who already engaged to another man at the time and only knew him for a few days. The film noir setting could justify this relationship as a form of comfort for Logan.
It's worth noting that Wolverine also only knew Jean Grey for a few days at mostnote (the first X-Men film takes place over maybe two days, then Wolverine goes to Canada to look around the Alkali Lake facility; in X2 he sees Jean at the mansion for a couple minutes, and then meets up with her again the evening before the big battle; then they see each other on a couple occasions in X3 when she's the Phoenix) and, more importantly, they weren't actually in a relationship. And that one's played as a romance for the ages.
Surprisingly Improved Sequel: Initial reviews seem to be placing it as one to X-Men Origins: Wolverine. It can also be considered one to X-Men: The Last Stand, since The Wolverine takes place after Logan was forced to kill Jean Grey, but it's more contentious to say so as it's not really an X-Men film and X-Men: First Class was also well received.
Not to mention the design itself means the climax devolved into a generic superhero CGI fight, that really didn't match the film noir tone the film had I tilt he very end. Most people would've preferred Wolverine fight a human-sized Silver Samurai.
Win Back the Crowd: The film discarded the previous Wolverine film and basically started from spin-off scratch, adapting one of the most famous comic arcs for the character and going for a smaller and more personal scale for the character. The result was far more well-received than X-Men Origins: Wolverine, enough for Fox to kick the tires on a follow-up with Hugh Jackman and director James Mangold returning.
