The bright spots: Will Smith and Margot Robbie were both great in it, though gangsta-style Harley & Puddin' were not as much fun as I'd hoped. (I have a feeling much of Leto's best material was left on the cutting room floor, an understandable decision given that they wouldn't want the Joker taking over the way he has a way of doing. But still... be interested to see what it looks like in a Director's Cut.) I actually quite liked most of the cast -- shame though it is to see Adam Beach wasted on a disposable character -- and thought Viola Davis was a perfect Amanda Waller.
I actually thought the take on Enchantress was very cool, at first. But her backstory and that of her brother as forgotten gods who want to take revenge on the world is so underdeveloped that audience members who blinked would have missed it. And her ultimate development was unwittingly comical. Not only that but the overall result here is that Project X starts out by taking on a problem
it created that nearly destroys the world, with Amanda Waller straight murdering a bunch of her own staff to boot. The Suicide Squad were anti-heroes in the books but they got more sympathetic treatment, and better bad guys, than this.
Reasonably entertaining popcorn flick, I mean, it's still better than the Fantastic Four movies. But nothing to write home about.
(I was amused to see Batfleck turn in a Nick Fury-style cameo in the end credit sequence.
