Boss Baby is definitely doing somewhere in the 30s, with a shot in the 40s. Weirdly enough, the Dreamworks movies that look like a chore to watch have overperformed compared to expectations lately, but I don't see it being as huge as something like Home or Trolls, with the Beast still being a monster.
Shell always felt like a mid-20s opener. Speaking as someone with no understanding of the original movie or the manga, I don't have a clue what the movie's about, why the setting's all weird and future-y, and why Scarlett Johannson has that weird bodysuit. Add on to anime being a pretty niche market to begin with, and it just feels like it won't do any good next weekend.
