Being a part of a focus group doesn't seem like it would be so much fun, but there's something about having your opinion valued that is really flattering.
My boyfriend and I showed up at CBS Television City, and we signed up to be a part of a focus group. They don't tell you what you are going to watch, but they give you a general idea of what genre you'll be reviewing. After we signed up, we got into line, and we didn't have to wait very long before we were taken into a room where we sat in front of our own computer. There was a big screen ahead of us, and our guide told us that during the show we were presented, we could evaluate whether we liked or disliked what we were seeing.
Afterwards, they gave us coupons and a free book. I'd go back if I were near the MGM.
