Just seen it today, here's my spoiler review
I thought it was a visually spectacular movie from start to end! So wowed by the Atlantis locales, especially the hidden area under the trench, and the city of Atlantis itself. Whoever imagined it all up sure put in A LOT of love and detail. Not to mention the dizzying 360 underwater shots during the underwater chase felt like a true thrill ride. I'm into rollercoasters so I really enjoyed myself. I wasn't too keen on the kaiju in Pacific rim, but the kraken here took my breath away for some reason - maybe the thought of Arthur commanding such a huge animal felt cool in itself.
The romance between Atlanna and Thomas Curry was so beautiful and bittersweet - surprisingly even more so than that of Arthur and Mera. It drove myself and my mom to tears (bear in mind that my mom hates the superhero genre - she surprised me when she asked to watch this movie with me, and surprised me even more when she cried through two parts in the movie. That hasn't ever happened before during an action movie, I think). As for Arthur and Mera, I know they tried their darnest, but there weren't many sparks between Jason and Amber. Sometimes actors have it, sometimes they don't. These two didn't, which was a little disappointing, but didn't hurt the movie much.
The relationship between the brothers was as tense as it should be and I really love how they ended it, how Arthur spared Orm's life, and they seemingly ended on good terms. That was really nice to see - rare too for movies these days (where the villain is typically irredeemable and they always die towards the end, in horrible ways). Orm didn't feel completely like a villain, his ecological message made sense, and I actually cheered when I saw that his tidal waves had dumped trash that had drifted out, back onto the beaches. Killing the king of the fish people didn't feel right though - but it didn't exactly make me hate him.
Similarly for Black Manta, I sympathized with him when he watched his father die in front of his eyes, and swore to not stop till Arthur was dead. At the same time, it didn't really tarnish my image of Arthur - it was merely an unfortunate event that pit two men against each other, which like real life - turns people into enemies. If we're getting tired of stereotype Marvel-factory villains, Aquaman managed to come up with two excellent villains with very rational reasoning behind their "villainy", in a single movie, which is no small feat.
The music was generally good, apart from two particular song choices that seemed a little out of place - nothing horrible though.
CGI was beautiful right up to the end where Arthur is riding the kraken, and something about the green screen made him visibly pasted on. That's my only complaint about the CGI.
8.5/10
