This is the 3rd entry in the "zoombies" film trilogy, and the MCU should be rightfully embarrassed.
In each film, the zombie plague occurs, just to animals, however, still leaving humans as the prey. No, the human victims don't seem to come back as zoombies themselves, they get to stay dead.
One thing to bear in mind while watching these 3 films (because, why aren't you doing that?), is that they were made on a shoestring budget. In this one, for instance, i laughed when a couple of characters were stopped by zombified river otters, which were apparently too complicated to animate by the SFX crew, because it cuts to the characters having run away from the otters and saying something like "wow, could you believe that?". I didn't, because i saw none of it on screen. I did appreciate, in this time, that they probably got the aquarium to film in inexpensively because it was likely shot during the pandemic, so there weren't any people visiting at the time. I bet we see a few more movies like this where ingenious film makers took advantage of hiring shooting locales on the cheap.
Other than just taking it all in and appreciating the goofy wonderfulness of these movies (certainly more entertaining than "sharknado"), which gets a little nod in this film because - sharks, it's silly fun, and that's all it needs to be.
