DC's "Legends of Tomorrow" premieres on The CW on Jan. 21, 2016. The American TV series is a spinoff of "Arrow" and "The Flash," -- so that gives us two reasons to be exhilarated.

A sneak preview of the show is already out, and it looks like it's greater than the sum of its parts.

The series promises an entertaining and enticing pilot that will hook the viewers to the show. Banking on its familiar characters that already have a connection with the audience, the show's ambiguous story will give fans of "Arrow" and "The Flash" a nostalgic vibe.

In the "Legends of Tomorrow" two-part pilot, futuristic character Rip Hunter time hops to the present to unite heroes and villains and rally them against Vandal Savage, an immortal Egyptians mystic who seeks to dominate the world.

The new series, which will be a universe of two established DC stories, will reveal surprising sides to well-loved characters. For instance, we will soon find out that Rip Hunter is Booster Gold's son -- making the time master an heir to centuries of heroic legacy. The plot twist won't be happening anytime soon as Booster has been set aside in the current cast list.

While he may meet his father and aunt later in the story, Rip Hunter will first collaborate with castoffs from "Arrow" and "The Flash" such as Ray Palmer, Sara Lance, Firestorm, Captain Cold, and Heat Wave.

Hawkman and Hawkgirl, who will have a role in the two-part pilot, will also join the pack.

"Legends" exist in a world where Vandal Savage must be stopped in order for heroes to triumph. Fan theories suggests that the Hawks are fated to completely destroy the villain.

Apart from the captivating story and the fierce antagonists, other reasons to look forward to the story are the interactions between establish personalities on board Hunter's time ship, The Waverider. For instance, Brandon Routh's Ray Palmer will be constantly annoyed by the Rogues while Professor Martin Stein will come across Jefferson Jackson.

Like in many "universe" plots, there's a worry that new viewers won't be interested in the show or won't be able to catch up with the characters.

Nonetheless, reports assure that the story will be delivered in a way that new audiences will be able to appreciate the story. After all, DC is well-love by different generations of comic fans. 

If there's a weakness to the first Legends of Tomorrow episodes, it's that, like most Marvel movies these days, it just expects audiences to know what came before. There is theoretically enough exposition to fill in new viewers on everything they need to know, but it's likely everyone would want to know more about these characters than you could glean from just these two hours -- or at least from the first act of the first hour, which is where everyone is introduced and decides whether they want to join Rip Hunter's crusade.

2016 is the year of comics. Many popular heroes will make a comeback and most of the will collaborate in a cinematic universe. Nonetheless, "Legends of the Future" is one project to put in your watch list.

The American television series was developed by Greg Berlanti, Andrew Kreisberg and Marc Guggenheim.
