That was my immediate thought. He played such a brilliant part, and so much of the comedy was the chasm between him and Frasier and Niles when it came to taste in pretty much everything - coffee, drinks, restaurants, music, interior design - to name a few.
I watched the episode not long ago where Leland Barton, Hester Crane's old research assistant, visits Seattle. Martin starts to wonder who is the boys' real father. He stands watching them all singing at the piano and so on.
I don't think I would watch a reboot. I love the old episodes even when I know them word for word, almost.
