The sun dried zombies was pointless
The Coyote when they first get in the city tells us about these sun dried zombies that when it rains they all come back to life, so immediately you assume "OK at some point its gonna start raining and fuck our main characters over" but it never rains once in the movie and those zombies are never brought up again.
Just pointless shit. Why even have that in the movie only to never use them? especially when you make a point to tell us "Ok when these things get wet they wake up" and then never have them get wet.....so why the fuck did you even need to tell us that?
Would be like if in Gremlins after the son hears the rules about what not to do with Gizmo, about never feeding him after 12am, never get him wet etc, and he never breaks any of the rules and the movie just ends with nothing bad happening.
