That's not what Holographic means in that context.

We've had holograms for a few decades. Why aren't you reading this on a holographic screen?

Antony Horowitz "Power of Five" series, is actually a remake of an older series called "Pentagram", which got cancelled part way through.

Can second that.

"And then there were none" is also the origin of the "Large group of people being whittled down one by one" trope, that - in my opinion - eventually led to the birth of the Slasher Movie. Which is interesting.

When they finally adapted The Big Four, for the David Suchet version... Well, it's one of the most interesting adaptations of a book to screen I've seen. Very different, but imo, very good changes.

I rather enjoyed it.

It has some obvious flaws, especially in the first couple of episodes.

But it was overall fun to watch, and I liked it. What more is there to want?
