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: Meet the Robinsons
Anvilicious: Anyone who watched the movie without realizing that the Aesop of the story is "keep moving forward" clearly wasn't paying attention and is blind and deaf.
There was a deleted scene in which Lewis takes Bowler Hat Guy back to the past with him to give him the chance to wake a younger Goob up in time to catch the ball, an offer he accepts with heartfelt thanks as he disappears from existence. Compare that to what actually happened in the movie, in which a nervous Bowler Hat Guy disappears leaving his trademark list behind, the final item being a question mark. Lewis later goes back to the past alone, and wakes Goob up himself, thusly flinging Bowler Hat Guy headlong into nonexistence. Keep Moving Forward!
Actually he's probably happy somewhere, maybe playing baseball. He didn't erase him from existance unless Goob died between then and then.
To explain, the Bowler Hat Guy was necessarily erased in that he no longer exists. Because Goob woke up, caught the ball, and won the game, chances are that his life is going to go into a different direction. The Bowler Hat Guy still exists, only he's not the Bowler Hat Guy, he's just an adult Goob who'll have probably had a better life.
Growing the Beard: While the move has its rough edges, Meet the Robinsons is now looked at as the start of the "Lasseter Era" and the turning point of Disney's Dork Age. Keep Moving Forward indeed.
Hilarious in Hindsight: At the science fair, Wilbur knocks over a box full of frogs and their owner makes him pick them all up. He isn't too pleased, calls her "annoying little girl", and she warns him: "I know karate". It's hilarious on later viewings when you realize the little girl is Franny in the past, Wilbur was calling his Mom an annoying little girl, and yes, she really does know karate.
Innocently Insensitive: Wilbur should probably be glad Lewis didn't overhear him telling Franny that "he (Lewis)" is an orphan; his tone is almost too casual and treats something deeply painful for Lewis as a footnote.
Moral Event Horizon: Doris gets one when she brutally murders Carl in order to steal the memory machine back. This foreshadows what happens to the future as a result of her and Bowler Hat Guy changing it very well. Fortunately both of these events get an in-universe Ret Gone.
No Yay: People pair Wilbur and Lewis. The weird time traveling incest doesn't put them off.
Squick: Ummm... well, at one point Lewis is almost adopted by his future wife!
And he calls her "Mom"... which is not helped by the fact that the studio took Franny's character model and covered it with a cloak for use as Lewis's mom.
Tear Jerker: The very end, revealing where the arc words were taken from, reduced many a sentimental viewer to tears.
Wilbur blurting out to his mother that he never planned to take Lewis back to find his mom, right in front of him no less. The opening music during that part is so heartbreaking that it makes one want to give Lewis a hug when he hides behind a topiary and begins crying.
Carl's brutal murder by Doris before the timeline gets fixed.
Wilbur fading from existance because of Doris tampering with the past.
