for free it is worth it
IMO it is the best of the 3 prequels the closest thing to ewoks and jar jar is the robot general. Still, it is not very good and nothing changes that.
For me it also got it out of my system once and for all. I guess closure is the best way to put it.
Some obviously put a higher value on their time than I do. Of course for me there is the matter of taking my three boys, plus it is a matter of what would I be doing otherwise. :)
