This Movie is all about finding hope, fun and will to live in a Zombie Apocalypse. It's silly, sweet and somewhat heartwarming amidst the chaos. In a similar fashion, this Japanese show is all about 6-7 young-adult trapped inside a mall in a Zombie situation. The show is more focused on finding love and fun, but if you like Zom 100 you may like it.
If Comedy and Zombie are your preferred genres, then Zombie-RomCom is a category you'd definitely love. The Korean movie is a twisted and funny spin on Zombies of (Jeong Bi), with a crazy man and his family trying to use Zombie to their advantage. Then Japanese Shows 6 Survivors or Ikinokotta 6-nin ni Yoru to is about 6 people trapped in a mall in Zombie Apocalypse. The premise in no way is the same, the genre does overlap with Zombies, Comedy, characters who care about other things more than survival etc.
