Years before the Syfy channel arrived on the scene to populate late-night cable with classics such as “Arachnoquake,” “Piranhaconda” and “Sharktopus,” there was “Highlander.” The 1986 film, starring Christopher Lambert as a Scottish immortal bent on tracking down and beheading the last of his kind, drew suspense from the slim logic that “there can be only one.”

Or several.

Of course, the very purpose of the “reboot” is to free filmmakers from the luggage of previous movies and sign on fresh talent. Ryan Reynolds has been confirmed as the newest immortal. The actor and heartthrob, 2010 winner of People magazine’s sexiest man award, has proved his geek cred by starring as katana-wielding assassin Deadpool in “X-Men Origins: Wolverine” and as Green Lantern. Geeks must be thrilled, right?

Perhaps it’s just love for the original and its score of suitably bombastic Queen songs that is driving the backlash.

On the other hand, movie audiences are weary of reboots in general: “The Amazing Spider-Man” opens July 3 with another take on the hero’s origin just 10 years after Tobey Maguire stepped into the role.

Nostalgia is selective, though, and not all are losing their heads over this bit of casting news.
