I think the contrast between the welcoming sign and the dire warning scribbled in red would be more effective if we could actually read the original text. As it is this is just a scary sign. The town in the background does look quite placid, but it’s almost invisible when paired with the strong and attention grabbing foreground.
Still, if you take your time and pay attention to the poster it’s pretty easy to understand the basic concept of the movie: small and peaceful town goes crazy, bringing all kinds of horrors. And even if you don’t pay attention it is still a fairly memorable, clean and direct poster. So not too bad.
I wonder if they intend to incorporate the hazard suits that were so present in the marketing for the original movie in upcoming promotional materials.
