Not my favourite. I love angst in love stories, I don't mind the uglier side of relationships, but not when it feels like the characters absolutely cannot stand each other. The arguments were too petty and too annoying and too cliché to actually build any sort of meaning or commentary beyond what we were given at face value. Yeah, alright, the movie proves love isn't a bed of roses, but it does so in an uninspired way in my opinion, then trying to salvage itself by throwing a few callbacks and clever dialogue about the relationship between love, life and time that all just mostly fall flat (even if there's some genuinely good moments in the midst of it all). Jesse and Celine work as a fleeting relationship, not as a long lasting one. In the other two films you could see they got on each other's nerves but it worked cus they were only in each other's presence for a brief period of time. This film wants so hard to be realistic, but there's nothing realistic about these two staying together for this long. The creator of this trilogy should have realised this worked better as a succession of one night stands.
