i also am fine taking in ambiguous endings and less rigid plot structures as a movie watcher but there were like weird very annoyingly minor details that kept me from sinking my teeth in

like come on bro in three years you know *nothing* about the shimmer? you couldnt just lock a pig in a cage three feet inside the shimmer and tie a rope to it to yank out after a week and see what happens? or park some machine inside and let the cord run back to home base?
