Questions/Observations.

1- I don't see a problem with it personally
2- Well he had to, if he didn't he would be dead and we'd have no movie
3- I guess he was so exited to be back he went temporarily insane and had a lapse of judgment
4- it's magic
5- well there you go
6- could be, we never get to see where Alan went - there could be a whole library
7- I always wondered that, that part used to scare me as a kid
8- is that confirmed? He could have been part of the game - I mean he seems to be from the 1800s yet hes still alive
9- I get the feeling he wanted his son to be more manly and 'normal' and he thought having a girlfriend fit with that
10- yeah that would be kinda weird
11- they were at a Christmas party and she was dressed up
12- yeah that was a bit of a coincidence
13- don't know her but she did well in the role

An older post, but:

1) I know that NORA is new to parenting, but does she really think it's a good idea to leave the kids alone with the exterminator? Do you think I'm exagerating? Well, he tells them about the myth surrounding ALAN's disappearance. The only reason to do it seems to be to scare the kids.

People weren't as uptight that sort of thing then.

2) The beginning stablished ALAN as a boy scared of many things... and we're supposed to believe he learned to survive in the jungle on his own?!

3) When ALAN returns to our world, he seems to think that time in our world stood still. Why?

I doubt he really knew how many years had passed. He probably should have, since he had grown an impressive beard. But he was back and his hope that his parents were there waiting for him overwhelmed him.

4) The pieces in the game stay in their place like fridge magnets, but the dices don't. How come they never fall down by accident. Also, the game isn't inside a box and doesn't have a lock. How come it never opens by accident despite the many times it's moved around?

Given its other properties its not surprising everything stays together.

5) I thought it was odd to have a pelican in the movie. Then I researched and it turns out that they can be found in Africa. Still, it's not an animal you associate with Africa (unlike lions, elephants, etc.).

No, but so what? The monkeys seemed to have prehensile tails, and monkeys from Africa do not. Only American species have prehensile tails.

Why not? It didn't say he was stupid. He did what he had to do to survive, as anyone would.

6) Just because ALAN spent 26 years in the jungle it doesn't explain how he's an fauna expert (e.g. he explains the difference between an alligator and a crocodile). Did VAN PELT have text books and he stole them? Is that the real reason why he wanted to kill him?

How do you know he didn't know before? I certainly knew the difference when I was 7 years old. Yes, I was a science nerd and collect

Sorry, for some reason MovieChat wouldn't let me continue. from where I left off.

How do you know he didn't know the difference before he went? I knew the difference when I was 7 years old. Yes, I was a science nerd. I absorbed that sort of thing. I was spout off dinosaur names to my kindergarten teacher. A lot of kids learn that sort of thing.

7) All the animals are sucked into the game. Would it have been possible for a human to be sucked by accident?

It is made pretty clear in the game that only things that come from the game go back when the game is finished.

8) VAN PELT got his gun in our world. Why was it sucked into the game too?

No. If you watch carefully the gun and the bullet start to "disintegrate" and are traveling away from Van Pelt. The gun and bullet went back to the store where they came from.

9) ALAN's dad sees that his son invited a girl over to his house without asking for permission and he's OK with that? Enough to think "Maybe we should have this conversation tomorrow so that you can go back to hanging out with her"? Actually, she arrived minutes after his parents left. Isn't that suspicious?

Why? These kids are young. I doubt his father thinks they have any "adult" interest in each other. As to her arrival, he likely assumed Alan had invited her over and she had shown up after he had left.

10) ALAN & SARAH grow up again as adults in teenagers' bodies. I think this could bring some consequences.

They were not adults. Yes, they had all their memories from the lives before. But Saran herself says, when they are throwing away the game, "Before I feel like a kid again." So, while they have the memories, they went back to being kids.

And to try to finish:

11) In the original timeline, JUDY wears a ponytail and then pigtails. In the new timeline, she wears her hair down with a couple of accessories. I think it was to show that now she was much happier.

Possibly. Or perhaps she just wears her hair differently from time to time.

12) I don't remember JUDY or PETER telling ALAN or SARAH how their parents died. Yet, they knew about it in the new timeline. They also never told them their last names. Without them, how did ALAN or SARAH knew to expect to meet JUDY & PETER again? And hy did they wait until 1995? They could've met them when they were born and maybe be close enough for their parents to consider them as godparents.

I would have to rewatch the film, but I thought they did tell them. Even if they didn't, I'm sure they mentioned their last name. And they told Alan that their father was in advertising. Given all that, it probably wouldn't have been hard to find out who they were. As to why wait, they would want to be sure to prevent the skiing trip. Bringing them in then would help that. (And its possible you are right and they didn't mention anything except the advertising. But even that, given that Alan and Sarah are wealthy, could probably be found out.)

13) The credits reveal that young SARAH was played by Laura Bell Bundy. What?! The country singer?! The actress from LEGALLY BLONDE: THE MUSICAL and ANGER MANAGEMENT)?! She looks so different!

People change as they grow. While it is likely that you can see the child in the adult, some people's faces change radically. And there is a tendency for people to "see" children and adults differently.
