Not very good. There are some things to like about this movie so let’s start with those.
I think most of the characters are well fleshed out especially Deadshot, Harley Quinn, Rick Flag and Diablo. I think those characters really shine in this movie and you understand their motivations and you feel bad for them. There were a couple characters that I absolutely hated though like Killer Croc (who is my favorite Batman villain) and the one person that gets his head blown off in the beginning. Killer Crocs character is horrible and he barely ever says anything, his backstory is explained in basically two seconds and they never dive deep into his story. The guy that gets his head blown off is just another person to kill. The only reason he was in this movie was to get his head blown off.
The story is a gigantic mess full of things that don’t make sense in the slightest. First off why are they sending a guy who can shoot people, a girl with a bat, and a guy who can throw boomerangs out to fight this big monster in the city. That just doesn’t make any sense especially because the Justice League was already formed. Why couldn’t Batman just assemble them to go fight it. Doesn’t make any sense. The villain is okay, they attempt to give her some backstory but in the end when they’re fighting her and she was doing her weird dance moves. I couldn’t take it seriously.
My favorite part of this movie is easily, (no spoilers) is them in a bar discussing their past mistakes and traumas. I think it was a very good scene and built upon the characters.
I’ve gotta dedicate a paragraph just for him. Jared Leto as Joker. I don’t know what they were thinking with casting him. He plays this weird kinda sexualized Joker and it was so weird I hated it. He just went so over the top in all the wrong ways and I hated it.
Suicide Squad is definitely not a good movie but I don’t think it’s the worst superhero movie.
