Critically, poor. But in terms of enjoyment and entertainment: a definite recommend.

Rating: 7/10 (16 March 2019)

I rate this movie using two scales. Critically and experience. Critically, this movie only gets a 2/5. But in terms of enjoyment and experience, freakin' 5/5. I know that the 5/5 is subjective because it applies only to myself and nobody else. However, this is what I think of the movie. If you're looking for a well-written, and greatly structured movie, then I wouldn't recommend this to you. But, if you want to watch an entertaining and fun movie that can keep you engaged for 2 & 1/2 hours, then you may enjoy this movie. I say that it's the 3rd best DCEU film, but most of the movies that exist (besides Wonder Woman) aren't good to begin with.
Now, the story was generic, the pacing was off, the dialogue was more cheesy then it needed to be. The characters don't have much personality, but rather exposition people. However, I really likeed Jason Mamoa as Aquaman. His charm kept the movie entertaining. Amber Heard actually did better than I expected, but just not anything special. Riddled with plot-holes and inconsistencies. However, thank goodness that it had the best DCEU villain so far: Ocean Master. So overall, critically, only a 2/5.
Now in terms of enjoyment, a 5/5. The visuals aren't perfect but they did a pretty good job with a movie that takes place underwater most of the time. The action was good (not for the underwater battles). The action scene of them in Sicily will hold up for a long time. The colours and effects were very engaging.
Ultimately, this movie was mainly about spectacle and excitement. So it really depends on what you're looking with this movie. Critically, it did not do good, which I hate. But I had a tremendously good time with it. Definitely not a 1/10 or 10/10.
