Should I watch the final episode of the original run? I've always avoided the last 5 episodes so that the show was never really over in my mind.

Or is the new season so shitty that I should just stay in the past and never finish the OG run?

Looking at the episode list, they are pretty random plot lines. I think the creators were told very late that they weren’t going to be renewed for another season, so they didn’t get a chance to wrap it up properly. But the final episode gets a little bit of a concluding send off.

I have read positive reviews regarding new season from semi-credible sources.
