- Ass Pull: Kyurem is able to change into its Black or White Kyurem forms at will, and can even switch between the two, without needing to absorb Reshiram or Zekrom like it has to in the games. The only explanation you get is how it can "harness their powers" due to being born at the same time as them, but not much more beyond that.
- Broken Base: While the movie is regarded as one of the better Pokémon movies by fans, there are those who dislike it for various reasons, such as the overabundance of telepathy-using Pokémon (of the five Legendary Pokémon featured, all of them use telepathy), the shorter-than-average runtime, a somewhat thin plot and the Pokémon outshining the humans to the point of rendering their inclusion unnecessary. There are those who actually like the Pokémon overshadowing the humans, the increased emphasis on characterization of said Pokémon, and the character development a good chunk of the cast gets over the course of the movie. Overall, fan opinion is basically split between those who were pleasantly surprised by the movie and those who still found it lackluster.
- "Funny Aneurysm" Moment: In an interview, director Kunihiko Yuyama thanks the fans for supporting the series and hopes that "you haven't felt betrayed by any of our movies". Come the very next movie, and many fans did feel betrayed thanks to Yuyama's questionable creative choices.
- Nightmare Fuel: Kyurem. As if his actual appearance wasn't enough, he has a habit of using an extremely predatory Slow Walk when stalking his targets that makes him quite imposing.
- Superlative Dubbing: Many fans prefer Vic Mignogna as Keldeo than the petite, female Shoko Nagakawa in Japanese.
- Surprisingly Improved Sequel: Many fans agree that this is the best Pokémon movie in years thanks to its greater focus on the Pokémon and its decent character development for Keldeo, Kyurem, the Musketeers and even Ash himself. Even those who generally dislike the anime have given this movie positive reviews.
