John Mendez’s review published on Letterboxd:
(Inspired by a section of Roger Ebert's review of Taxi Driver.)
Travis meets the girl of his dreams, then he takes her to a porno film.
He sucks up to a senator but he ends up alarming him.
He tries to befriend a prostitute, then scars her in the end.
In all of this moments of the film, Travis tries to make a connection with someone and ends up ruining that connection.
You talking to me? You talking to me? Well I'm the only one here.
When he is saying this line, he is ultimately talking to himself. Showing his utter loneliness.
