Virus premise doesn't gel

Ok, animals are non symptomatic CARRIERS. For what I understand, a carrier doesn't allow much reproduction to the virus, till it's carried in a victim. I mean, the virus needs the HOST, not a carrier, to replicate.
Like, it needs to affect the host to make it infectious and replicate.
If it's in a carrier, it just travel around without doing much, waiting to get into somebody to infect. If it goes from a carrier to a carrier to a carrier, it will stop being a virus at all.
So for this logic, if it's just being carried around by animals, it will stop to be infectious after people disappear for some years, because it doesn't have the breeding ground to infect and replicate.
That's what I understand.
I'm not debating that the movie has lots of merits, I like it quite a bit, but this premise seems a bit cartoonish that's all I'm debating.

Hey anything is possible, especially if you believe fake news.
Meanwhile, in the real world, viruses work in a way that makes sense, and the deadlier they are the more difficultly they spread, since the host dies.
Also,like you mentioned, if it propagates with asimptomatic hosts, that means that a large part of the population has no problems with it. You wanna tell me that surface civilization would stop in such a case?
So, again, the premise does not gel.

Yup, even when the whole world is pretty much wiped out...they put all their effort into sending crazy dudes back in time.

Ok, your genetic engineering concept makes more sense than a regular natural virus.
So, it's meant to be super deadly for humans but not to other carriers.

In that case, it's ludicrous that they wouldn't identify the carrier pretty quickly, and get rid of it/neutralize it/isolate it. Or is it a magical virus that infects EVERYTHING but only kills humans? Come on, let's be scientifically accurate.
Not only that, but even if it infected lions and bears, those are sparse and not in contact with humans.
Any possible host that will give problems to humans is another animal that lives in close quarters with humans, like rats, pidgeons, pets, fleas, mosquitoes, flies and that's about it.
Any of these animals are easy to deal with and isolate, they could just start some hot spots here and there, but like already mentioned, it's a super deadly virus so any hot spot is self cointained.

So we're back to square 1, even with a genetically engineered virus the doomsday premise doesn't gel.

And yeah, time machine but no vaccine, way to go geniuses!

I agree. I also think there are species-specific viruses. I recall an outbreak of canine parvovirus that is highly contagious among dogs and was causing a lot of canine deaths but not killing cats or humans for example. I don’t have a problem with the virus premise in this movie in which it only kills humans but not animals. The terrorists who created the virus were partially motivated by anger at scientific animal abuse; a subplot that ran throughout the movie. It would make no sense for them to develop a contagion in a laboratory to punish humans for such abuse and then unleash it only to kill all the animals along with the human targets. You are a voice of reason here

That's not the way it works, not even in this movie.
The crazy guy had it contained in what looked like a frozen cylinder. It was meant to look like a microbe stable in those specific conditions, that once opened had a few minutes to get places, infect somebody, or die.
Air is a totally different environment than that cylinder.
Covid is quite easy to control, we don't even need Bruce Willis nor Biden, just social distancing. Of course if you have an idiot in charge that doesn't want to wear a mask because of his 2 cm penis complex, than that's a problem.

Good Call Einstein! More people died of Covid under Biden than Trump. What a great job! About as good as those mayors in NYC and California that persuaded people to defy Trump and go to the movies and Chinatown, only to clog their hospitals with more people than beds just to scare people into pointless lockdowns (oh wait, there was a point, remember mail in ballots?).

I kinda got the feeling this is not a documentary too, thanks for pointing that out....
Ok so it's stable on surfaces and enters the skin: that's a bitch!
But wouldn't rain wash it off? Or at least some tonnage of cleaning products? Or worse case, hazmat suits and gloves. Doesn't sound that difficult to fight afterall.

I like this movie, I'm just pointing out that these scientists, who have the capabilities of constructing a time machine, don't know how to fight this virus, probably because it doesn't even make sense.

Maybe it goes along with the crazy subplot: the virus itself is crazy and the way it works is crazy too!

Yes, that is a probable scenario, but any writer in 1995 would have told you that's so stupid and incredible it's difficult to have viewers buy into it. Anybody watching would say "can't they wear their fucking suit properly and stfu?"
These fools would probably wear the hazmat suit half open, hanging from their waist, with the mask pulled up on their head.
That's as useful as a condom tied up around the base of your dick, but guess what: that's exactly how they use their condoms! Which explains the overabundance of morons on the planet.
And then gather in big crowds to party up, because you know it: civilization cannot go on without partying at all times, during wars, revolutions, holocausts, pandemics.....
