It has been a long time since I've watched any. The movies after the first cancellation were okay; some were better than others. The episodes after the revival weren't as good and defintitely relied to much on direct reference. The 3 episodes I remember most clearly are the "iphone" episode, the "susan boyle" episode, and the "garden of eden" episode. Perhaps the originals had something similar and the references are just too old for me to be aware of.

I would only be interested in an HD restoration along the lines of what old Star Trek got.
