Good fighting scenes won't make up for bad story

Rating: 4/10 (12 August 2016)

I was utterly disappointed by this movie.
Story: I could totally picture the script-writer seeking for a good reason for bad guys to save the world > didn't find any > and just went: "Ok, what if they say 'let's save the world' (not a spoiler) despite being completely OFF CHARACTER? I think the public won't care".
And the worst "WTF" part, for me, was when El Diablo said "they are my family"... (I'm not telling when or why he said that). Again, the script-writer was probably short on ideas and went for the most improbable action, thinking "the public won't care...", again...
BUT I DO CARE...
---------- Spoiler ON ----------
Same for the 'persuasion scene' where authorities just had ONE demo from the MOST POWERFUL of the "villains", and then just went "Ok, you can build your team"... dude, really? one demo is all it takes? knowing the others are not as good? You sure trust the script- writer, I mean... Amanda.
And what about the almighty boss who mysteriously sucks when facing them... so infuriating.
---------- Spoiler OFF ----------
The humor: Good sometimes, but forced on us other times. Trying to look cool like Deadpool or Guardians of the Galaxy maybe?...
The characters: Harley makes sense, the rest is still searching who they really are I guess? Bad or good? I personally think it should be the case. And the JOKER... is a joke. I couldn't find the "intelligence" I loved in him in previous movies/comics/animations. He was just crazy... and vapid.
Conclusion: To me, the story is empty and has to many "shortcuts". It doesn't hold at all. The characters are undefined/unfinished. The action scenes are great, although unrealistic sometimes even for meta-humans. But not enough to reach the 5/10 note for me.
In the end, I almost left the theater twice and the action scenes were the only things that made me stay. The last time this happened to me, was for Once Upon a Time in Mexico (2003)...
PS: I'm not judging the work or the opinions of other spectators, THIS IS ONLY MY PERSONAL OPINION/FEELING.
