I found Suicide Squad to be a fun-but-flawed film. If it had been released prior to the MCU’s explosion, it would have probably been better thought of.
For the record, I thought Jared Leto was good (though I can see why others would dislike the characterisation). 
The Night of the Demon
I must thank Mike for lending me this one. The Night of the Demon is a cracking 50’s occult horror/thriller.
