I especially like this one about whether or not it's okay to receive free product to review. I keep seeing this discussion over and over again about whether or not it's ethical for a reviewer to critique books he or she got for free. Some critics have even gone to the extent of disclosing in their reviews whether or not they paid for the book. I think that's unnecessary.
Of course movie critics get tons of free DVDs, just as book critics get books, etc. You may review those you want, even going so far as to pay for those you don't get for free. Recently I ordered the complete Werner Herzog documentaries from Germany, for example. Herzog would no doubt have been happy to supply them, but I would have felt like a creep for asking. If I admire him so much, I should be willing to buy them. Your unwanted DVDs must never be sold, unless you are a starving critic, in which case you are exempted under the La Boheme amendment. Technically, you should put a scissors to them before discarding, but I don't think the FBI will come after me if I give some to our grandchildren, or donate them to a veteran's hospital.Amen to that "don't sell your unwanted comp copies" bit. I know some critics see it as deserved payment and I'm not going to argue with them, but a) I'd feel icky doing it and b) Ebert backs me up, so that's where I stand personally.
I also love Ebert's thoughts on being prepared to give negative reviews even to friends. Man, that's hard to do. The best I can usually do is just not review something if a friend wrote it and I didn't like it. Ebert's bravery is inspirational.
