Action is excellent but story line is OK but downfall when combined with the dark style

Rating: 7/10 (4 April 2016)

I read lot of comments of this movie before I finally went into cinema. I have to say that the movie is better than the most of saying especially the action or fighting part. I love them very much.
Many friends told me that the plot or story line of this movie is bad or too simple to understand. Batman and Superman somehow hated each other (though the movie do give explanation but it is weak indeed) and they fought and suddenly after Batman heard the name of Superman's mother they became friends. Yes, the story is simple but the story is always very simple in super hero movie and so do the Marvels movies. Therefore, the plot is OK as I thought.
So where is the problem? I thought that the problem generated from the style. If the movie goes like so darkly and so seriously, I may intrinsically consider that the movie wants to discuss something very seriously like value of being hero or to show something complicated, but it does not and hence mismatch people's expectation.
Last but not least, the Wonder Woman, is very attractive and fascinating. It is definitely the first time that I saw a main hero role in screen as woman. She is so elegant and sexy.
