Even though the release isn't due until December 21, Warner has shown an early version of Aquaman to a test audience.

Batman-News says it spoke to audience members who'd seen the movie and that comments were positive, with one viewer calling it "an emotional action movie" and saying the tone was similar to Wonder Woman.

Bodes well, but let's not forget that fans who saw early screenings of Suicide Squad also went crazy for it.

MILD SPOILERS TO FOLLOW...

Warner Bros.

Directed by James Wan, who made Saw, Insidious and the Conjuring movies, and starring Jason Momoa in the lead role, early whispers say Aquaman is a little bit scary (with some underwater monsters) and has a strong supporting cast.

Patrick Wilson is apparently a standout as Orm, aka Ocean Master – the main villain – while Yahya Abdul-Mateen II plays secondary villain Black Manta.

Batman-News reports that Black Manta's costume and origin is the same as in the comics. His signature look is a black wetsuit and a bug-eyed helmet though he has more than one origin story...

One involves being kidnapped as a child and taken aboard a ship where he was systematically abused, growing to hate Aquaman for failing to hear his calls for help. In another he was an autistic orphan who grew up in Arkham Asylum, who became fascinated with Aquaman after seeing him on TV.

Aquaman's love interest Mera, played by Amber Heard, also received praise, saying she's more of a co-lead (perhaps like Steve Trevor in Wonder Woman) than just a romantic role.

It all sounds very positive and we have faith in Wan as a director, particularly if he's been allowed some creative control. But then again, fans who saw 30 minutes of Justice League early said it was better than Wonder Woman and that Marvel should be panicking... Just saying.

Aquaman opens on December 21.
