The Icky Eccentric Movie 'Willard'

I just happened to see this movie in HBO right now and it's a bit icky because of all those rats! But I continued watching because the story seemed so interesting! Would you believe you'd be able to get rid of the people you disliked by letting the rats have their way with them! What a horrible death! But such is the way that happens in the movie. And, the funny part is, they play Michael Jackson's Ben - his song about - you're right - a rat!
