The premise is simple: a fledgling actor decides he's done with life so he hires a camera crew to follow him around, documenting his final living days. After he is gone, well, there will be a record left behind. His own self produced reality show of the end. His friends mostly just assume it's a cry for attention - you know that's what people like him do, they need a spotlight on them, overdramatic, etc etc. He looks fine.
Like many actual reality shows there is a lot of unnecessary side drama which seems forced / manufactured - it even seems to take over at times, you'd think that would be mentioned in any truly negative reviews it gets. Sometimes there is a lack of real character development, maybe that'd be mentioned in truly negative reviews. Most of what I have seen in negative reviews is just vague or instead focuses on the mental illness / depression aspect. For me that is not at all an issue having actually lost a friend to suicide and having dealt with many more people who have dealt with different forms of depression / other mental illness. To think someone who "looks normal" isn't ready to end it is pure ignorance. Everyone is different. The person I know who did kill themselves did so as their life was going better than ever, when people complained the least of their depression symptoms affecting those around them. Our star here was clearly bottling something up, as seen in the rare alone with the camera moment we get to share with him.
Of course like many people with depression issues he has alienated most people by the time of his big day - those who don't believe him seem sick of his silly ways, those who do just don't want to be a part of his plan or his life / death in general.
So will he or won't he? Obviously death is his chance to end it, get famous, it's the solution... it's also final and he won't be around to enjoy it, no second chances. No spoiler here.
Is it a fantastic movie? I wouldn't go that far, but it's also better than some of the reviews I've seen that seem to make it out as the worst thing ever given to humanity.
