What the new Justice League trailer is really revealing about the DC universe's future

With their biggest splash of a preview since last year’s San Diego Comic-Con — and a year to the day since the release of “Batman v Superman: Dawn of Justice” — Warner Bros. and DC Entertainment have released a new “Justice League” trailer.

There are no signs of Superman’s return from the dead, or of top DC baddie Darkseid, yet the most striking aspect here might well be the occasionally light — dare we say “fun”? — tone of this trailer.

The path to the formation of the Justice League has been a dark one, yielding few laughs in between movies (unless you count the few minutes the Joker was yukking it up in “Suicide Squad”).

Judging by this nearly three-minute trailer, however, WB/DC is heeding the need for a shift. Beyond director Zack Snyder’s typical special-effects flash and panache — and sometimes cringe-worthy dialogue — it looks as though some life is being injected into this party.

Yes, DC is ready to lighten up a bit.

Plus, unlike the trailers for “Batman v Superman,” which sometimes contained so many spoilers (including the appearance of Doomsday), WB/DC is smartly holding back on any Superman or Darkseid footage.

So for now, we get a look at Batman, knowing that the threat from Apokolips is real — and we require uniting the meta-humans to form the Justice League.

The rest of the trailer is a lot of action with the current five members of the Justice League (Batman, Wonder Woman, Flash, Cyborg and Aquaman) backed by the rockin’, on-the-nose “Come Together.”

“Justice League” arrives Nov. 17.
