For me, the only episodes that I tend to skip are Captain's Holiday, Who Watches the Watchers, The High Ground and Transfigurations. So that's 22 out of 26 that I enjoy watching. I can barely find 22 enjoyable episodes in seasons 1, 2, 6 and 7 combined.
Heck, they had an episode that focused on Wesley and Lwaxana Troi AND featured the Ferengi and still managed to make it entertaining. That right there is a writing staff that can do no wrong.
