@socketwench - Something I'm very big on telling people is that a lot of early Classic Who is SLOOOOOOOOOOOW. Because we're a binge watch culture now (or got used to the "omnibus" versions in the past), we tend to sit down and watch every episode at once.

Early Dr Who should be watched, at most, one episode a day. It preserves the cliffhangers, makes you want to watch the next part, and takes a slow boring 3-hour-6-episode slog and turns it into a weeks worth of event viewing.

When I moved in with nerd roomies, and they saw my collection of classic Who, they wanted to see the first Dalek serial. I warned them it's a long six episode slow burn, but they wanted to see it anyways. They got so bored so quick.

But when I showed them the Dalek Invasion of Earth, I did it one episode a day for a week, and they were all into it.

We tend to forget that these are serials, designed to play out over a month, and often stretched out to fit that month. They make for exciting 30 minutes chunks, but very boring 3-hour movies.

Around the mid 70s there was a concerted effort to go into four episode serials and only occasionally get into 6 episoders. Mainly so they'd have more "First Nights" but a side effect is you now had 1.5 hour stories that were quick, concise and work for binge watching.
