I wanted to switch this off after first 10 minutes, but my wife wanted to give it a chance, so here i go...
Main problem is how unlikable main character is. People in the movie try to cheer her up or have meaningful discussion, but her favourite response is always "You should go now" or similar one word answer. Its very slow paced, with completely no character development at all, aiming nowhere and it doesnt have reasonable conclusion either. This was marked as comedy, but there was no single funny moment.
Maybe if you enjoy to watch clinically depressed, emotionless person, which doesnt even try, for 90 minutes, then this movie is for you.
This is rated 6/10 on IMDB and i had strong urge to controbute to rating correction to where it belongs - 3-4/10.
