- Author's Saving Throw:
- One of the first films most major criticisms was that its characters, especially Surly, were all too selfish and unlikable to care about. In Nutty By Nature, the characters have all become significantly nicer and the constant backstabbing from the first film is completely absent, making the sequels tone a lot less mean-spirited.
- Though Surly no longer belittles and bullies Buddy in this film, its revealed that they first met when Surly saved Buddys life during a hurricane, which explains why Buddy remained attached to Surly despite his constant abuse in the first film.
- Cliché Storm: Even worse than the last film. All the humans are portrayed as money-grubbing villains who don't care about the environment or the animals, the animals decide to band together to fight the humans, the Big Bad hires an exterminator to help him kill the animals, the main villain has a bratty, annoying child, there's a Love at First Sight subplot that ends with the couple having children, the movie takes a dark turn in the second act where all hope seems lost, and in the end, the animals win without suffering any casualties, and all the villains are thrown in jail.
- Crazy Awesome: Mr. Feng. He's a loose-cannon who throws a fit whenever he's called cute and is generally unstable. He's also a highly competent fighter who leads a large army of mice, all of whom are strong enough to fight off human beings.
- Funny Moments: When Mayor Muldoon hears from a police officer that whoever built Liberty Land is going to be arrested due to the numerous safety violations, he knocks the police officer out right afterwards and tries to get away in a hot air balloon. In other words, this dumbass only digged himself deeper.
- Like You Would Really Do It: There was no way Buddy was going to die from a fall, especially considering Surly and Raccoon survived very similar circumstances in the last film.
- Narm: Andie repeatedly reminding the animals (and the audience) that they're wild animals and should act like it, instead of being lazy and trying to take the easy way out. She makes a good point at first, but after repeating the same message over five times, it just becomes hilarious and can't be taken seriously. It also doesn't help that the film can't decide if it's on her side or not, and repeatedly undercuts her point (her collection of nuts is just sad, and at the end she's even given a Not So Above It All moment with the nut cart).
- Rescued from the Scrappy Heap: Andie went from being an annoying Lawful Good character who believed in Black-and-White Morality, to a Wide-Eyed Idealist who constantly keeps the animals of the park in line and lifts their spirits whenever things seem grim.
- So Okay, It's Average: How some fans who didn't dislike the movie see it. The movie doesn't try anything new or groundbreaking, is very cliché, and focuses more on over-the-top destructive sequences and comedy over the story and characters. Nevertheless, the film is still enjoyable and harmless for what it is, the movie doesn't contain overly preachy or contradicting aesops, and most of the cast is likable.
- Squick: Frankie regurgitating his food so Precious can eat it, only for Frankie to eat it when she refuses. Precious understandably throws up too, and said vomit is also eaten by Frankie.
- Surprisingly Improved Sequel: Or in this case, Slightly Improved Sequel. Many consider this film an improvement over its predecessor due to it toning down the pessimistic vibe, the characters being more heroic, and for having better comedy. That being said, both critics and moviegoers still agree that because it doesn't replace the mean spirited tone with anything worthwhile, the film is still far from great.
- They Wasted a Perfectly Good Character: Mr. Feng. He's featured heavily in the film's advertising, but ultimately serves no purpose besides being a Chekhov's Gunman during the climax, where he and his army of mice free Surly's friends and largely contribute to fighting off Muldoon's men. Considering his tragic backstory about him being driven out of his home, a lot more could've been done with him.
- Uncanny Valley: The animation for the human antagonists can be rather unnerving at times.
