I don’t read the comics. A friend of mine read them and said the show did a way better job with characters and pacing (he hates amber though) so I probably never will.
But i hear the comic is actually really long. Like it would take almost 10 seasons to cover everything. With how common stream show cancellations are, I find it hard to believe the show will ever get that many seasons. Not to mention animation is notoriously time-intensive. Even if we got to the 8 seasons needed it might take 12+ years to animate everything if we go by how long it took from season 1 to season 2…
Show Amber is a vast improvement over comic Amber so far, your friend is nuts.
I don’t know if they’ll make it or not. Hour long episodes of a Western animated action series is kind of uncharted territory. Amazon has had some shows that lasted a while at least, they aren’t as cancel happy as Netflix. If it does stop you should be able to easily pick up the books where they leave off ad get the rest of the story.
