Napoleon Dynamite
Words cannot express how amazing this film is, from so many different aspects it inspires me to create and to make something that I believe in, you can tell that the director of this film was a film nerd and that he believed in what he was making even if it's basic on the surface, what he's made is a gift to cinema and to those who value films in general, it's genius simplicity and attention to detail is something every single up and coming artist/creator should take inspiration from, this is truly the ultimate indie film, from character design to the soundtrack (goat soundtrack btw) to the shot angles, it is beautifully put together.
(Fun fact: This film's production budget was just $400,000 and it made $46.1 million, that explains a lot about why it's so phenomenal, he made something very ordinary seem very extraordinary.)
