Throughout the third season of The Flash, much of the central narrative has seemed to center on the questions of exactly who Savitar really is, and what he has planned for Barry Allen – which are, basically, exactly the same questions that we had with the previous central villains of previous seasons. Despite the writers' best efforts, and some genuinely great moments, it just isn't something I have found to be terribly interesting.
In fact, it has even seemed that Savitar works much better as a vague, and distant, threat than he has as a primary focus. The character, himself, might not be all that interesting, for example, but the lingering threat of his eventual murder of Iris West has provided a strong sense of focus as we move toward the season finale.
More than anything, it seems that this threat is also at the heart of the season's eighteenth episode – as a new villain from the pages of the comic-books makes his first appearance. Abra Kadabra (David Dastmalchian), as he calls himself, is a flamboyant show-man from the distant future, who uses highly advanced technology in a way that appears to be magic.
