I hate all of the lame CGI BS bullcrap in the prequels. They had potential, but George toy-boy Lucas threw that potential in the trash like a piece of food......
For instance, for Mustafar, why not use a real volcano, or at least a bit/lot less CGI??? Maybe like that volcano from the lords of the rings movies. Mount Doom. That area looked real. Mustafar in star wars episode 3-revenge of the sith looked like some high-tech play station 3 video game.......
film it in a real location, for god's sakes!!!!
