Amusing in parts, but so many missed opportunities...

Rating: 4/10 (5 August 2016)

Saw this at a preview last night. If I'd paid to see it I would probably have been more disappointed than I was.
Let's get the good bits out of the way.
Jared Leto as Joker. He's not Heath Ledger, but he didn't play the part like Heath Ledger did. He was...different. And quite disturbingly so. Yeah, he did alright.
Margot Robbie. Her character was just about the only one with any back story whatsoever, and consequently (aside from her being gorgeous and having the best lines) she was the only character about whom I cared.
Spoiler: Diablo. Great character, some back story, some actual depth (even if he was a walking cliché). But he's not going to be in the inevitable sequel, unless he has some other special power we don't know about. And how the hell did he suddenly become what he did at the end?
Deadshot. Jesus, Mr Smith. Are you that skint that you have to take whatever is offered, and that arrogant that you then just phone your performance in? You were out-acted by a headless corpse hanging from a climbing rig.
The rest of the characters, including the main not-really-good-woman and the main not- really-bad-villain were utterly two dimensional. Y'know, like they were drawn in a comic.
This could have been a great movie. It had a great cast and a really good premise. But DC really need to watch a few Marvel films and learn how it's done...
