The overused and bad CGI is the main issue with this prequel trilogy
If the CGI and special effects weren't so bad and obvious, they'd be so much better. It's amazing how the original trilogy can be made 25 years earlier and look better than this trilogy. I read that every single clone armor was CGI. Why is that necessary? To save a little money? I'd understand if they use CGI when they show thousands of clones at once, but when there's just a couple on screen, or even just one, use real freaking armor and costumes.
And then some of the fight scenes are just insanely bad. The Yoda vs Sideous fight looks like a crappy video game.
It's the same with the Hobbit trilogy and Lord of the Rings. In LOTR, most of the orcs are people in costumes and make up, and they look real and terrifying. In the Hobbit, it's all crappy motion capture, and they look fake and laughable.
