Garbage. Absolute A grade, badly edited, badly put together, semi-nonsensible, un-progressive plot Garbage. After seeing the extended cut of BvS (which is awesome) I had high hopes for Suicide squad, but it looks like David Ayer (the director) and the exec's at Warner Brothers butchered it.
The best parts had Batman, the Flash or the joker in. each got no more than 60 seconds of time on screen. Leto's Joker had definitive brilliant Menace to him, Batman was great and the flash for his brief cameo was great... but, everything else? no, just no.
...just, awful, I am deeply upset by this.
