"Even the people who love me hate me"

I work a later shift, so I spent the morning watching the ANTON CORBIJN film "CONTROL" on DVD.
A chronicle of JOY DIVISION lead singer IAN CURTIS, the film is more about the dissolution of a marriage and the disintegration of a life than it is about the rise of Britain's most influential band of the post-punk era.
It's tough viewing, seeing Curtis subsumed by an overwhelming cocktail of inadequately treated epilepsy, depression, and anxiety and guilt about a prolonged, extramarital affair. Corbijn takes starkly beautiful, iconic photographs, and the film's look follows this lead.
SAM RILEY plays Curtis and convinces as the frontman battling fatigue and fear.
I just wish the film had fleshed out the Curtis character a bit more.
I have been an avid follower of Joy Division since high school, and I know from extensive reading that Curtis was famed among his bandmates for his humor and especially his love of practical jokes.
"Control" doesn't give us a glimpse of this side of the main character, however, and I felt a little let down at the end.
Surely, there's more to the man than a suicide waiting to happen?
