THE GOOD THINGS
The tone of the film is much more "bright" and fun away from what was seen in "Batman V Superman" and including many moments of humor mostly from the character of Flash this makes the movie more fun and fun and full of allusions to moments and characters of the DC universe that most fans will surely appreciate, including (albeit briefly) the melodies of Batman and Superman from the original films. It has a lot of action and although some scenes stand out more than others, those that work do it very well, in this movie you will see moments that all the followers of these characters have always wanted to see.
THE BAD THINGS:
The first and most striking is the little personality and the null charisma of the villain Steppenwolf, a character totally generated by computer that fails to produce tension in the story and leaves much to be desired. The obvious lack of footage is very clear and this translates into scenes that occur without much or no explanation in between and that leave you with many doubts, this can be checked by taking a look at all the trailers issued and you will see that there are many missing scenes. The CGI is excessive and not too bright in some occasions so much that at times it seems that we are watching a video game. The characters are unbalanced because we need to know something more than some (Aquaman or Ciborg) others maintain the level (Wonder Woman and Batman) and others are out there in the middle (Flash) there are even enough that only appear a few minutes or even seconds , clearly that obvious cut of footage has been primed with them.
In short, as you can see the bad exceeds the good but still the movie is very spectacular entertainment and will make you spend the two hours it lasts in a sigh, probably the most fans come away with the feeling that this movie is a step back in the seen with "Wonder Woman" but a more complete and enjoyable work than "Batman V Superman", I'm sure we will see a more "complete" version of this film as it happened with the extended versions of "Suicide Squad" and "Batman V Superman" and hopefully DC can remedy and rectify and give us a second part much better than apparently in his second post-credit scene are on track.
