The film looks great, thanks to the new generation of special effects. But neither the story nor the characters prove particularly compelling. Many adults will find him annoying enough to wish someone would slice him in half with a light saber. Lucas always expressed frustration that the available movie technology could not transfer his vision to the screen. Maybe that's part of the problem.
Limitations can stimulate the ingenuity of a great artist.
The lack of them has, in this case, exposed a certain banality. This one really is skewed toward kids, deficient in both the philosophical and romantic resonance of the earlier movies. The movie's chief problem is an uneven pace that sometimes slows to a crawl, which may be the result of a story that seems to lack a sense of urgency. As for Samuel L. Jackson as Jedi knight Mace Windu, don't blink or you'll miss him. Neeson projects the air of mystic calm appropriate to a mature Jedi, but it hardly makes him distinctive.
