I think it did pretty well in the UK, so it’s likely. Actually, I thought the ending was kind of weak, and way too much of a set-up for a sequel (especially concerning his kids and their HEROES-type emerging superpowers). But overall, an excellent show, and Nesbitt was awesome. I’m up for more.
Not with Nesbitt, so if there is a follow up, it’ll be a long time coming. Still, having been a fan of the book since I could read, we’re looking at ages of guessing. I think it’ll stand as a one off, hopefully noted as a good idea.
