Here's the problem

Rating: 7/10 (5 August 2016)

The movie itself was actually decent on it's own legs. Jai, Smith, Robbie, everyone put in as good a performance as you could expect. No one seemed like they were phoning it in. The visual effects were good. The plot was shaky, chaotic, and disjointed; however they managed to bring it back together before it got lost in itself. A decent 7 in comic movies.
The problem is that they are basically starting their DCEU run by making joint movies instead of stand alone movies. The biggest complaint across every recent DC movie is that it loses focus trying to introduce characters and backstory. BvS was 3 iconic stories and 2 introduction stories mushed into one film. Suicide Squad is no different.
A big part of what being a DC fan is about is the deep storytelling. We know about The Joker because he's been methodically laid out to us. All of these villains have just as rich a story, but we're getting 1/4 of the potential in a messy montage. It's unfulfilling, upsetting, and it's why DC is losing.
On a personal note, I hated the deconstruction of the Joker from smart, crazy philosopher to badly dressed gangster. It felt like they had no idea what to make him say or do. I know he's not supposed to be a big part of this movie, but what they had him do felt maligned to every previous Joker in history. To be clear, I'm blaming the studio, not Jared Leto, and I don't even like him.
