A few reviews

[Malthus]

Although the "Immortals" in 'Highlander' aren't really immortal, they can be beheaded by other immortals who are constantly hunting them, which effectively negates any alleged effect on the dramatic stakes. Also outside of the threat, or lack thereof to the life of our hero Connor, there is the threat that the evil Kurgan could win "the prize". So yeah, you can have "immortal" characters and still have tension if you tweak a couple of other plot elements.

That's fair. I have a thing for immortality. I'm currently working on a novel which features immortal consciousness. So characters live and die before being reborn with all prior knowledge intact. They still need to adhere to the standard human life cycle so every 50-80 years the needed to re-go through puberty etc.
