OP, I think you’ll find a lot of fans here who agree with you. I am one of them.
Not only do I find ROTS absurdly overrated, I think it’s amongst the very bottom of Star Wars films and just a bad film in general. From the ridiculously easily duped and stupid characters, to the ugly video game esque visuals, distracting fan service and OTT saber fights, horrible dialogue, odd clashing tone of bouncing between childish humor/uber drama, and the rushed awkward ending… it’s all just a mess to me. And don’t get me started on the butchering of Vader’s fall (which ties back in to stupid characters).
