I just finished watching Anne Happy.
Overall, it was very disappointing. Simply put, it wasn't very good.
The main reason I picked this up and sat through 12 episodes is that I was very intrigued by the premise. The characters are all uniquely unlucky (luck is a major theme in the show). They are all enrolled in what is known as "happiness class", where you learn to be happy (despite one's misfortune). I really liked this premise and thought it had potential.
I'm also conducting a systematic review of anime that aired in 2016 on account of me being severely autistic.
I quickly realized the poor quality of the show, and mainly watched it as a low priority "filler" anime for when I was too tired and just wanted to stare at a screen but not watch anything I actually cared about. I also would put it on when in a depressed mood to try to immerse myself in the happiness class setting.
Anyway, the reality of the show is that it is extremely unfunny. Unfortunately the screentime is dominated by low quality comedy. The characters themselves and their interactions are all lame. The art style is lame (silver link also was a factor that enticed me to watch this). The OST is lame. The production quality wasn't terrible or anything, it's just that the content fundamentally wasn't good.
The positive:
Some might find the absurdist aspects of the show funny or entertaining. The character designs are kind of cute (though lacking in variety).
5/10. Wouldn't recommend unless you're obsessed with SOL comedies.
