Mediocre

Rating: 6/10 (23 December 2018)

Ignore the 1/10 and 10/10 reviews, this movie is not better than The Dark Knight (9/10 IMDb).
Using common sense, the best Aquaman can be is a 7/10 given that (IMHO) it's not better than Wonder Woman (which has an IMDB rating of 7.5/10).
Now on to the spoiler free review itself.
The Good:
1. The visuals
2. Jason Mamoa (distant 2nd)
The Bad:
1. The overall story
2. Character Development
3. Forced dialogue/jokes
4. Unnecessary plot points, which probably help contribute to
5. Undeveloped story arcs
The Ugly:
1. The Manta story arc
There is a lot that I didn't like which I can't get into without going into spoilers.
