what would have made this movie better?

The acting was fine, it's just that some of the characters were weak. Stephen was, like Tristen said, a bitch. A self centered, whiny little bitch. I didn't care for Erica either. Nice little piece of eye candy but the whole Wicca crap got old fast. She was the type of person who drones on and on about the single interest in their lives and will never shut up about it. They manage to find a way to work it into any conversation, regardless of the topic. Strip more, talk less. I didn't really care for Kim at first but I warmed up to her once they all got back to Jeff's place. Unlike the other two she had a decent personality and seemed like a nice person at heart. Jeff was an interesting character and Donovan played the friendly, if slightly unhinged tour guide well. Tristen was my favorite character. Her acting was the best and I also found her to be the most attractive of the three women. Craven was a good character as well and I enjoy any role that Lanny is in. For having as little screentime as he had in Signs he still delivered.
