Entertaining but let down by weakeness of script and characters

Rating: 7/10 (15 August 2016)

I went to see this with no expectations good or bad.
It is worth a watch, I found it entertaining. However, I came away with a sense that this could (and should) have been so much better.
If you like the genre you can turn a blind eye to many short comings but this film felt half made. The plot so banal that it was probably written on the back of an envelope while taking a dump.
In short : Government fears another 'Superman' may not be a good guy (didn't actually explain what happened to Superman).
So create team of criminals with superpowers (or no superpowers) ready to fight any super baddies.
To make sure they behave insert explosive device in neck that can be remotely detonated.
One of team is possessed by 'enchantress' a thousands of year old being with unknown powers. She manages to get away and co- incidentally finds long lost fellow brother being. Together they begin to create mayhem.
Criminal team sent in and beat bad guys then go back to prison.
What i liked :
Will Smnith as 'Deadshot' and Margot Robbie as 'Harly Quinn' both stood out in their roles Jared Leto as 'Joker' also (but not quite) with a similar portrayal to heath ledger except the character seemed under used.
What I did not particularly like: The other characters were pretty much un-inspiring to the point of boring. Cara Delevingne I found particularly annoying and illustrated that 'eye candy' is not a substitute for an actor. Viola Davis as 'Amanda Waller' didn't come across as tough/ruthless.
All in all, a few good characters and a crowd of boring ones, looking for a plot.
Entertaining but unsatisfying 7/10
