Do you stream your TV? If so Tubi has the entire series and Tubi is free/non-subscription.
Good quality too, good audio and video. Re-watched the whole series on cable about 15 years ago and the quality was horrible. But I loved the original (didn’t miss an episode) and wanted to see it again.
I think streaming has got to improve before I want to use it.
I am, sorry to say, spoiled by DirecTV. As much as I despise their politics, you can just with a couple of clicks find out about actors, writers, directors and sooo much more.
When and if, streaming improves, I’ll be there. Now, I use it sparingly. A problem usually arises to disrupt viewing and it turns me OFF.
