I recently had my first go-see-a-movie-in-the-theater-alone experience which was fun and good and totally something I would do again. I think it helped that I saw a movie that I was really, really into, and kind of can't stop talking about.
Frances Ha was co-written (the other writer being Greta Gerwig, the star of the film) and directed by Noah Baumbach, who has done other gems like The Squid and The Whale and Margot at the Wedding. The film essentially follows the life of Frances, a 27 year old aspiring modern dancer who is trying to figure her life out in NY. The film heavily focuses on all of the weirdness of being a sort-of adult, including dynamics surrounding close friendships- I really enjoyed was that although there is some romance in the plot, all of the major growth in the film is friendship based- as well as not being able to pay rent, not knowing when it's time to get a 'job' job, etc.
It's cringey and funny and touching and I heartily recommend it. Here's the trailer, in case I haven't sold you yet.
