Classic Who is similar, except the action is toned down, the pacing is far slower, and it's very much a refined and more family oriented experience. If you can put your mind in the times when it came out, you will be able to maximize your enjoyment of these episodes. They are like a very aged whiskey, where the flavor might be slightly dull and the barrel tones are much more evident. It's smooth and relaxing, something to sing you a lullaby instead of get your blood flowing.
That's the closest I can get to describing the old show for you. You have to be ok with slowing your brain down, getting in an older mindset, and then they are fully enjoyable.
