This entire series was messed up. Every season disjointed from the other and all of them having various major flaws. But sure, S3 was “OK” although I feel pretty much over that enemy… I’m not sure how they still don’t suspect it’s starting to feel stale. Also, fan service was over the top with unbelievable scenarios conveniently bringing everyone instantly together.
The main feature is that you’ll never have problem with too few or no seeders again, and everything will be fast always, and no one will ask or expect you to seed. Some have retention period on the content for like a decade.
