First off this film is sort of a remake or a reboot of the franchise. It tells the stories of the previous films but intertwines them to form a cohesive film. I really don't understand the bad reviews. It's an entertaining film with decent scares(maybe a few too many jump scares)and an interesting story. Some of the acting is soso but overall not bad. The movie has a few very suspenseful moments that lead to legitimate scares. It also changed enough of the old stories to keep fans of the first set of films interested. I enjoyed the movie and thing it is highly underrated.
