Since I'm a cinema-lover, I watch a lot of artsy and experimental stuff, and I also go pretty often to the Toulouse's cinematheque in order to see a lot of great, old movies. (They air a lot of horror movie !) So, I go most of the time alone, since my girlfriend isn't really into cinema that isn't big and fun american blockbusters, or japanese animes, or french comedies.
And it's great. Going to watch a film on a sunday morning is sooo good. There's almost nobody.
It's not weird to do that. Of course cinema is supposed to be a public's experience. You're supposed to be with other people that you may or may not know, people are supposed to whisper, to eat, there's a lot of sound, you can hear the projector, etc.
But sometimes it feels good when the only thing you hear outside of the film, is the sound of the projector, it's pretty magical.
