While I do agree it has a very strong focus on suggesting more of what you've recently watched, I feel it's also managing to suggest new and interesting unrelated stuff from time to time.
Some habits I have is to subscribe to channels which I truly enjoy, instead of marking as "not interested" I select "do not suggest channel", and be cautious of click-bait titles. If I get lured in, I remove them from my history.
So for me it's mostly great, though I get your frustration as well. For example I recently watched a couple of informative videos on the LA fires as I have some relatives living in the area, and suddenly my feed is tons of that and little else.
