My TNG rewatch marathon was rudely cut short when my bluray player stupidly broke after a mere 2 years of use.
I had just rewatched season 5, and after only skipping a few episodes, such as Redemption Part II, Unification Part II, New Ground, The First Duty(I like this episode), Imaginary Friend, and Time's Arrow, I enjoyed every episode I did watch, except I Borg. 20/26 good, thats a pretty good batting average.
When I rewatched season 4 I had also skipped the episodes I don't enjoy watching; Family, Suddenly Human, The Loss, Q Pid, The Host, In Theory, and Redemption. 19/26 good.
Here are my rankings from the previous seasons that I rewatched.
Season 3; I don't like Evolution, The Ensigns of Command, The Bonding, Tin Man, Transfigurations. 21/26 good.
Season 2; I don't like The Child, The Outrageous Okona, Unnatural Selection, Time Squared, Manhunt, and of course, Shades of Grey. 16/22 good.
Season 1; I'm not a fan of Encounter At Farpoint, Lonely Among Us, The Last Outpost, Justice, The Battle, Angel One, and Home Soil. 18/25 good.
