Being an Alia Shawkat fan, I had to watch this. And I must applaud her, not so much for her performance here, but for her guts in taking on a role of a character who is going to be resented a lot as a narcissistic ego case who is a drag on everyone else.
When you start watching this, you think this movie will be the classic Slow Motion Train Wreck. Those are fun movies, because you know the disaster will happen, and you get to watch and satisfy your curiosity. But it doesn't happen. Instead a new band member Pat arrives and changes the tone from hopelessness to one of positivity. So the movie becomes a "personalities under stress undergo changes" slice of life movie. That's a hard movie to make, I think, because the interactions have to "smell right" -- that is, be believable to a deep extent, so that you KNOW that what is happening HAD to happen, because of the characters, and there have to be AHA moments. But it doesn't make it. Too many tiny question marks pop up, and this ensemble doesn't pull it off. I have to blame the director for this, because there should have been many scenes done differently and subtly and edited better, and maybe it could have been pulled off. Again, I think the task was gigantic and this crew just could not pull it off. Unfortunately, failure in this case makes the film such a dreary watch that a lot of the audience is going to tune out, walk out, or otherwise bail.
