If you've ever read the book or seen "Trainspotting" the film, you know that it gives an unfiltered look at what heroin addiction is and its effect on people, all through the eyes of the main character Mark Renton. In a very similar fashion, "The Party's Just Beginning" gives you a glimpse into the hellish world of depression.
Karen Gillan did an amazing job writing and directing this film, which is especially surprising (and awesome) because it's her first. As a directorial debut it's a hit, but even from a seasoned director this would easily be a winner. Like any film that deals with such a specific and supremely dark subject matter (and being so bleak as it is), it's certainly not going to win everybody's heart. However it's that bleakness that Karen managed to capture which really resonated with me, and is portrayed so well, both in the film's characters and its substance.
In fairness, I must admit to some bias, as I've always found Karen gobsmackingly beautiful. With that said, if you've ever struggled with depression, this is likely to resonate with you. And if you're like me, it's going to leave you crying and writing good reviews. Finally worth mentioning is that the last film I gave a 9/10 to was "Pulp Fiction"; indeed, I liked it that much, and I can't say enough good things about it.
