Yes, I believe this title represents this anime the best. However, I suppose it does require an explanation.

1. First of all, it is a rare bouquet of vidid characters, clever plot and lots of tension and suspense. There may be a few dragged out scenes and some that could be considered "cheesy", but... it's not your regular anime, it stands out and doesn't rely on the common tropes. Hence the overall comparison to something as impossible as "lightning in a bottle".

2. However, what is lightning? Can it truly be... suspended in a bottle? No, obviously not. Lightning is a force of nature, and the series presents us with very meticulous, sometimes downright annoying worldbuilding, but... sadly nothing comes out of it. What does lightning in a bottle look like? A fancy custom LED. This is pretty much how all the world building feels in this series - very, very intricate, yet very, very downplayed.

3. Finally - what is a bottle? Obviously it's a very tight space. This is because the biggest problem is that the protagonist, who drives the plot, has to be... himself. That's as much as I can say without spoiling anything. He essentially has lightning in his hands, his potential - limitless. But throughout all of his ordeals he has to remain... himself. The ultimate prison. As much as 75% of the plot could be unraveled and discarded if only the protagonist would drop these shackles and embrace his goal.

Additionally, this series suffers from a curse of anything with a limited runtime: series, anime, movies... The curse of rushed resolution. A lot of the best works of art in this category begin by bringing out the biggest guns, the most intricate and interesting plot. They captivate the audience and give the illusion of quality. But... the bigger you build your world, the more the looming truth of limited runtime digs in. And you have to write yourself out of it somehow. Obviously the manga doesn't have such constraints, but this series - do. In fact so much that... it's basically necessary to watch Death Note Relight 1\2. Again, that's as much as I can say without spoilers. The series is wonderful, and it must be watched in its entirety, because it still has the highest runtime, however, because of the fact that it relies on post-series content that merely retouches the... uhm... "subverted expectations", without truly fixing the issues of the "lightning" and the "bottle" - I give it only 8\10.
