I agree with you somewhat. But it really seems to me that nowadays, whether in movies or TV shows, people want and expect there to be a twist. Without them, they're 'boring'. I can't tell you how many reviews of films I've read that basically said, 'The whole movie was great, but I kept expecting a plot twist at the end, didn't get one, so it blows chunks'.
Even Survivor and, to a lesser extent TAR, have their share of twists. So I've just resigned myself to the fact that I have to accept them.
