I like your point about Emily Blunt. I absolutely loved her performance in the Jungle Cruise I've just watched. Then, I would like to speculate on some of your points, but before that - I haven't seen the film. I saw something else with the same premise, but the creatures were vulnerable to cold, so there was a refugee in the sub-arctic regions.
First, why the sea-separated nations don't do anything - from your lines, my guess would be, that #1 the creatures are unreasonable strong and #2 everything collapsed so fast that Hawaii, Japan, Australia, and others haven't had the time to develop any weapons. They might struggle with their own population as all the supply chains are disrupted, so is the people's way of life. What political consequences might that have on one's country? #3 The filmmakers in America sometimes forget that there is a world outside America. If it started in America and the creature can't be contained & put into a cage, even Euroasie should be fine, right? #4 Provided that Europe and Asia have, for some reason, also fallen even though they are not connected to America by land, the rest of civilization might choose to starve this creature. If they breed so fast they caused a collapse of both Americas and Eurasia, this sounds like a sound strategy. Especially if every source of food is thought to be completely wiped out on these continents.
The second, the choice of weapons. #1 I think if the creature hunts by sound, it should very vulnerable to sonic weapons. Some frequency could kill them the same way the whales can kill us and that's only 120-150 decibels. Something louder than that, running at the right frequency, should do fine which takes me back to 1.1, the creatures are probably unreasonable strong. #2 Another cool weapon type any advanced country has at its disposal now are suicide drones. They are designed to be silent & travel hostile territory undetected. Producing the loud versions would be cheaper and it sounds like a weapon perfectly fitted to fight these creatures.
Anyway, I think a lot of these post-apocalyptic movies have too many problems to take care of, so they just ditch some of them. Or in other words, how dare you suggest there should be something, that an advanced society that has had nukes at its disposal for decades, could do! And that's another interesting plothole right there. What happened to all the weapons of mass destruction? Dead-hand of Moscow would surely be activated by an event of this magnitude, wouldn't it?
This movie seems to be quite popular, but I still fail to see why. If you like post-apocalyptic shows, I came across Tribes of Europa not so long ago. Their world is a lot more believable and it's quite good for a German sci-fi series.
I will be watching that movie soon, it is on my to-watch list and it appears most people liked it.
They should try to kidnap one of these creatures to experiment on it. They certainly have the resources to do that.
This could certainly be the case and that brings the potential for some spin-off or something similar showing how those countries collapsed. Nevertheless, I believe most countries must have some type of reserve that allow them to run for several weeks or months.
Explaining this would be a spoiler but islands are the places where things should be fine and safe. Europe and every big continent is probably destroyed too.
What you mention about weapons, the safe island countries could very well do that and weaponize the sound. But nope, the only case of sound being weaponized is by one of the main characters and it happens by chance.
All of this is certainly a plot hole but again, this could be solved if they decide to produce spin-offs to show what happened in other places but who knows what the producers decide to do with this apocalyptic world.
I have read about the series Tribes of Europa but haven't watched that show yet, I might do it in the future. This movie is simply a well-done action film packed with a few intense scenes with the monsters.
There is a cool French series where civilization collapses called L'Effondrement, it has no scifi or fantasy it is mainly realistic drama and it kind of explores that question you asked there. You might enjoy it but the reasons for the collapse aren't completely explained it only shows events that happen during the collapse. Very entertaining.
Try 15 days at most. Countries with higher canned food consumption might have a little more and islands can still go fishing. But the world's food reserve is far smaller than most people think.
And they may not necessarily collapse, but strict rations and other necessary measures would be hard to implement.
Something I haven't mentioned earlier - I think only Japan has highly sophisticated weapon manufacturers (from Islands). I can't imagine Iceland or Hawaii developing any kind of arms.
I am grateful for your suggestion. It looks decent and I wouldn't find it without you. I rarely watch non-scifi non-fantasy stuff, so it doesn't appear in the recommended for me.
The collapse wouldn't be that different based on the reason, would it? I strongly doubt that. Anyway, my bet would be one of these: monetary system, cultural tensions, solar storm, or food crisis.
Tough day at the supermarket for this young clerk who tries to keep calm and do his job seriously while many products are out of stock and public paranoia rises.
That's the description of the first episode of L'Effondrement. Sounds a lot like an economical disruption. I can imagine a few things that could do that.
Yeah, it is almost like an anthology because each episode shows different characters experiencing the collapse in different manners although a few characters appear in more than 1 episode. For me, it was very realistic and some parts were intense. It was a unique and enjoyable show for sure.
It would be the same but I would still have preferred some info about the reasons behind it.
Have you checked out an Apple TV series named "Calls"? It was one of the most unique productions I have seen this year and it shows a very different type of apocalypse in a very special way. It has suspenseful scifi even though all we see on the screen are animated waves representing the emotions of the people talking during the calls. It was cool.
I've checked Calls on IMDb just now. It looks like a show for some artificial intelligence, not for me. But I know someone who might love this uncommon format.
Nope, it isn't about AI. It is about events that might seem paranormal but have an apocalyptic scifi background unrelated to AI. Just in case, this is the imdb page https://www.imdb.com/title/tt9327706/ and trailer :P
