You are wrong for a hundred reasons, but I'm just going to list three.

The over choreographed fight scenes in the prequels lack any emotion, compared to the original and new trillogy. Who exactly was Kylo Rens sparing partner? Much like Luke in the original trillogy he had no one to spar with so his saber skills was raw to say the least.

The reason why there was so much variation in ship design in the prequels is that Lucas is a business man first and foremost. He wanted to sell toys, this wasnt so much apparent in the original trillogy, but was clear in the prequels, he would shoehorn as many ships and characters into the franchise just for the purpose to sell toys.

If you are focusing on the design of ships and costume design then you are missing the bigger picture. The story of the prequels is none existent, overly complicated and makes no sense. Check out my article on the Phantom Menace highlighting a lot of the problems with the movie.

The force awakens isn't perfect and essentially a soft reboot of a new hope. I didnt care for rogue one. But the new films are considerably better than the prequels.
