I agree, it's too bad Hills (8/10) couldn't have opened higher. While the numbers aren't bad, I wonder what misfired. Afterall, as Madsen said, horror is hot right now, and about this time last year The Amityville Horror remake (7/10) opened to over 20 million, and I don't think that looked better than HHE. Still, the numbers are nothing to cry about, 40-45 million is a decent final gross.
Let's just hope that when the weekend actuals are released Hills edges out Shaggy Dog, although even that might be wishful thinking.
