However, it's been years since I sat down and watched the series in its entirety, and so I decided to change that. Instead of watching every episode of the series, however, I sat down and figured out how to condense the show's 2nd through 7th seasons to 20 episodes each and will be using this 'streamlined' approach as I rewatch the series.
Arbitrarily restricting the later seasons to 20 episodes each is not "the series in its entirety," which was what you apparently intended to do originally. But you didn't, so you didn't really change anything. How do you determine which episodes get included, and which are not worthy of your time?
I tend to agree with your 'Emissary' evaluation.
