The prequels should have started with the Clone Wars, covering more of Anakin and Obi-Wan’s relationship, with an occasional flashback to the earlier Anakin to fill in his past. Being a fan from the early years, I didn’t like the prequels that much initially, but the story grew on me after watching them a few more times later along with fan commentary over the years. What I do still think they suffer from is making Anakin’s fall too sudden, and if we got a better sense of how much he and Obi-Wan were brothers in spirit, the eventual fall would mean more. There would also be more room to develop the friction he observes with the Jedi Council, maybe even take things to a new level in why they don’t let him progress. I guess I basically see TPM as a wasted first part to better establish his character.
My hot take on the sequels is that the first one was a decent start, and they screwed up the whole plot from there. It had some issues mainly in dropping subplots, probably because what was intended to be followed up wasn’t thanks to different plots and directors.
