“Suicide Squad” is a 2016 American action hero movie based on DC comics.
As always, just a short teaser from wikipedia here:
In the film, a secret government agency [...] recruits imprisoned supervillains to execute dangerous black ops missions and save the world from a powerful threat in exchange for reduced sentences.
So it is basically the default super-hero installment one already knows from Marvel or DC. Nothing special.
On rottentomatoes, the movie scored only 4.9/10. I rather like these kind of action hero movies where one does not have too much to think. The movie was not dumb, with some nice action-scenes and a few funny dialogues. So I would rate it with a 6/10.
