Visually stunning but suffers from poor writing and execution.

Rating: 4/10 (29 December 2018)

I went to see this film with medium to high expectations after reading some stellar reviews on IMDB. I would advise checking the date more closely because DCEU are clearly using the reviews before release as a guerilla marketing campaign.
Don't get me wrong. There are some saving graces. Some of the scene design in this film is wonderful. Atlantis looks stunning and some of the fight scenes are entertaining to watch. However there is inconsistency in how well underwater scenes are rendered and it does sometimes lend itself to video-game cut scene territory. Also some of the costume design looks straight out of old-school power rangers which I'm not sure is a good thing for multi-million pound production.
Where the film suffers most however is in the the god-awful dialogue. If you're a fan of overblown cheesy declarations, this film is for you. If you wanted something more punchy and impactful, this film is not. I heard a couple of audible groans from the audience at a couple of points after the characters make wooden use of already cheesy lines and it really is almost laughable.
Jason Mamoa does his best with the material given and he really looks the part! Nonetheless though he struggles to deliver on some of the more 'cheesy' moments where he is required to emote something more than 'cool surfer man'. I'm unsure if this is due to the bad lines given, poor direction or due to limited ability. The baddies are a bit forgettable and could have used better motivations over all. Mantis was given one but was underused and a bit ridiculous really.
In summary I wouldn't pay to watch this film and I wish that I hadn't. Read the real user reviews folks, check dates and stick to the MCU I guess because apart from Wonder Woman this DCEU is simply not up to par.
