While I do think the prequels had some potentially interesting ideas (and TPM actually felt very visually inspired to me, unlike AOTC and ROTS), they’re otherwise genuinely terrible movies in almost every way. I cannot conceive how anyone other than children could find enjoyment from watching them. These movies have the opposite of chemistry or relatable characters, and even the action scenes are ruined by being overblown visual noise.
So, yes, the prequels are bad, and you should feel bad if you like them unironically.
A part of me wishes that there could be a large-scale fan project, a “replacement” trilogy featuring completely rewritten scripts and practical effects. Would be very expensive (especially with all expenditures being out-of-pocket, since crowdfunding would be illegal), as well as difficult to find consensus in the writing as there would be so many different ideas of how it should go. Ah, well, I can dream.
