I read this and I wonder if they made it past the first disc.
They get better as you go. I'm not sure but maybe that's because when they made each episode back then they got better at what they were doing. This was a pretty innovative release at the time and it took about 2 years to get to Episode 5. I remember waiting for each to come out and watching them unsubbed after getting them from unofficial sources a day or so after. The anticipation!!!
I watched it on my 4K TV using an Oppo BD player.
Overall this is an excellent improvement over what has been released previously.
Two thumbs up- Siskel & Ebert.
