I totally get where you're coming from. I found the first episode by far the least enjoyable to watch, due to a combination of the tension and the monotony. I still liked it, but it was nowhere near as enjoyable as the subsequent episodes.I love music documentaries, music history, and I really like the Beatles.
But I got 3/4 the way through Ep 1 and had to stop.
I mean, I've been in band rehearsal, I've done the sitting around trying to come up with ideas for songs. It's fun to do, but boring to watch.
