For those of you still wondering why the box office has been rapidly declining over the years, it’s because of weekends like this. Three new films open on Friday, two of which are remakes, and the other which might as well be. The reimagining of Wes Craven’s classic 70’s horror flick “The Hills Have Eyes” probably has the best shot at topping the box office, but it’s hard to count out a kid’s movie (“The Shaggy Dog”) and a romantic comedy (“Failure to Launch“), both of which have equal ability to upset the always financially successful horror genre.
