I like Nogizaka46 and try to watch a lot of their videos, so I also wanted to watch a documentary to learn a little more about the group. Although the title is "How To Forget Sadness: Documentary of Nogizaka46," it seems like the vast majority of the documentary was spent showing members just crying.

If you have watched any other Nogizaka46 show/movie, you will have noticed that the entire production focuses almost entirely on just several members while everyone else is cast aside. I really don't like this system and this documentary is set up no different: just a handful of members are showcased or even shown for more than 0.5 seconds, and everybody else is completely omitted except for group shots.

If you really like the group and you have a couple of hours to kill, you can watch it.
