Will & Grace is a great show and will continue to be so even after its gay theme loses its novelty. The writing is usually great, sometimes exceptional, the hour long flashback episode was the best thing I saw in the 2000/2001 TV season. But I would credit the cast most of all. Eric McCormack is (comparatively) subtle and nuanced as Will, Megan Mullally bizarre and sharp as Karen, but I reserve my highest praise for Debra Messing and Sean Hayes. Hayes' Jack is endlessly energetic, always plotting, and watching Hayes' performance is like watching a Van Halen guitar solo, almost too fast to follow but every note perfect. Debra Messing's Grace seems to be the character that everything happens to, and you can see every bit of it on her face. Her bio tells of her extensive arts education, and it shows. If there's ever been another Lucille Ball, it would have to be Debra Messing. Will & Grace has all the necessary sitcom ingredients: interesting situations, hilarious comedy, and characters you care about.
