Seasons 4-6

Watch the entire series again, right now, and tell me there aren't dull moments. In 2022, I would make the episodes 30-50 minutes rather than 60 minutes, and probably cut out at least half the storylines. Basically everything from Adabisi's death isn't worth watching.

It doesn't hold up well imo. I would agree that it was revolutionary and instrumental in getting The Sopranos (which I'd say is the most influential show of the past 25 years) off the ground, so it deserves credit for that. There's a lot to like about Oz, but ultimately, I wouldn't recommend it to anyone in 2022. It's way too long of a show and there's a lot of dull moments.

If there was some kind of abridged version that was around half the total length of the series (so ~25 hours), that would probably be great and worth watching.
