Natick/Framingham have excellent movie theatres, not to mention Mall-Land.

Here's my thought. If this was the perfect place for you, you wouldn't be asking anyone else's opinion. So this isn't perfect; what is? The question becomes, is this good enough? Does it make you happy?

You may have to give up one of your goals: either "house perfectly configured for the parties" or "house central enough that friends will come even when there's no party scheduled". What's most important?
