Reanimator = hidden gem
Best recent one= train to busan
Undisputed best= original Romero trilogy especially dawn, also the reamakes are pretty weak they substitute all the cool social messages with senseless action.
I also like the first evil dead but I thought the second one was too silly.
Warm bodies and zombie land had a cool different take on the genre, didn’t like so much 28 days later, maybe I should rewatch it since it’s so highly regarded.
