It might take some getting used to the grandiose and somewhat campy tone of DC’s new “Legends of Tomorrow” — but if you’re watching, you’re at least a little familiar with it from network-mates “Arrow” and “The Flash,” from which “Legends” is spun off.
The plot goes like this: About 150 years from now, the world is hell, overrun by a mad despot — who happens to be immortal — named Vandal Savage (Casper Crump). As the series opens, he busy laying siege to London in “The Second Blitz,” as it’s called. Oh, and apparently we’ve discovered time travel by this point, because a lone voice of reason (Arthur Darvill) is appealing to the Time Masters Council to let him go back in time and put together a team of heroes to help him defeat Savage once and for all.
