Amen!
I've not been boycotting the entertainment industry. I've just been buying tickets for only worthwhile shows. The result is very nearly the same as a boycott. Most of what is produced is amusement only. a - the Greek prefix for "not" and muse - Greek for thought. That is, it keeps you from thinking and dumbs you down. That's not something I will pay for. I don't even pay for T.V. Get a book and keep your mind sharp.
That said, if Alec Baldwin, Barbara Streisand, and Richard Gere were all in "The Return of the King" (Please tell me it ain't so) I would still go to see it.
Shalom.
