WB Failed Aquaman In 4 Different DCEU Releases & Set Him Up For Disaster

Aquaman's DCEU swansong was nowhere near the success of his first solo movie, and the franchise film-makers themselves deserve some blame.

Aquaman's cool factor was undermined in the DCEU due to comedic meta-gags and repetitive insults, impacting Jason Momoa's performance.
The DCEU's insults towards Aquaman in previous films, including Justice League and The Flash, contribute to the de-cooling of the character.
DC's anti-mythologizing of Aquaman was a mistake, as it detracts from building up the character's mythology and undermines his impact before The Lost Kingdom's release.
