The idea of living in a tv show, where your entire life is made up by a director, is overwhelming in itself. In the beginning of the movie, it really makes you think about life itself and it brought so many philosophical questions to my mind. Witnessing how the people he considered friends, and even his own wife didn't actually care about him was heartbreaking, as they were all just actors.
That being said I believe so much more could've been done because they had such a brilliant idea behind it. The ending really leaves you wondering and I just can't help but wish for more. Although I thoroughly enjoyed it, it feels unfinished in my mind. Either way, even just for the idea itself and how well it is presented, it's totally worth the watch.
