There's a grand scale of majesty and I'm fascinated enough by the story world below the sea. Very VFX apparent throughout. Very stretching of believe in terms of characters' strengths and prowess.
I loved seeing Aquaman riding the seahorse. And I like Topo too! And my favourite bit is where we learn how rulers should be building bridges.
Jason Momoa's performance made me imagine what a cinematic Lobo would be like, rather than the Aquaman from the comics I know (esp. the Peter David written stories).
