So, /vp/, I've always entertained the idea of downloading every season of the anime and watching ever episode sequentially (never mind Chronicles or Origins), to sort of "catch up" with how things are.

The problem is there's over a thousand episodes. Or 18 days straight of continual episode watching without any breaks. Not to mention I'd have to download it all.

I wouldn't mind doing it if each and every episode presented actually relevant plot developments. But from the little I have watched its mostly a mix of "cheesy situation, beat team rocket, wash, rinse, repeat", with the odd evolution or team addition thrown in.
So it's little wonder I look at that number of episodes and nope the fuck outta that idea.

1,000+ episodes is a bit daunting. If I could narrow the list down to about 250 or less, of the most important episodes, I'd be more willing to do so. Anyone up to the task of sorting the treasure from the trash? Also, are the spinoffs any good/worth my time?
