Definitely better than the original.
Though admittedly, that is not difficult to achieve considering how bad the original was. Overuse of slow motion scenes and felt really draggy. Score was good but as the movie itself had no emotion a good score has nothing much to elevate other than the more epic scenes.
Overall, the movie was better fleshed out but in no way is it close to being as good as Avengers or any Marvel film. I would not even say it was the best DC film as I think the first Wonder Woman film was a better movie.
Not a masterpiece that many have claimed it to be. But a step in the right direction for DC films.
