A few of the actors in the prequels did what they could, and I accept that creating prequels for such a great trilogy must be hard. And Ill even give GL credit that yes, he did actually do something a bit new (even if it wasn't very good), as compared to The Force Awakens, which was too derivative.
But in general, GL changed too much of what made the original trilogy good, and put in too much that was nonsensical or childish. I kind of feel bad for Hayden Christensen and Jake Lloyd, too. Most of the other actors had to some degree established themselves so they could 'walk off' these terrible movies, but both of these young guys got no direction and had terrible lines.
But in one way - they were a bit prescient. They exhibited about the same quality as Disney "direct to video" productions.
