Tiago Cardoso’s review published on Letterboxd:
What kind of young person am I? Like Scott Pilgrim vs. the World (2010) Richard Ayoade’s Submarine is a coming-of-age story (indie version) that focuses on the lead character's views of his world through the lens of his interests. And like The Graduate (1967) uses water as a metaphorical representation of the main character entrapment. An opportunity for self-discovery.
