It's not a question of trying vs. not trying, but possible vs. impossible. They know how time travel works (in this movie), and nothing can be changed. The pandemic is going to happen no matter what, because it already happened. Whatever they did in the past already happened also, and didn't make any difference.
What they did in the movie is beside the point. A series would be a different take on the concept, a different continuity, and thus free to reinvent the concept in whatever way suits the series' needs. Just like virtually every TV adaptation of a movie ever made.
Quite right, as I acknowledged in post #25. The comment you quoted above was about the movie specifically.
I'm not disagreeing, but the key there is "in the context of the movie." Given the television show would also be from his perspective and that they don't necessarily have to follow everything from the movie, they're free to toy with this idea and even change the rule. There's no reason for the audience to already know the answer, especially since the movie audience didn't definitively know the answer the first time watching it (precisely because we're following Cole's POV).
I refer the right honourable gentleman to the answer I gave a moment ago.
