I’m glad Lucas did this. Otherwise it would have been Celebrity Star Wars.
Plus he would risk jumping the shark.
Perhaps he already has as I have not seen 2 and 3.
Unless you have a taste for a combination of moronic dialog and incredibly bad acting which no amount of special effects could save, don't bother. That shark was jumped, stumped, and beaten into a coma.
2 and 3 are both worth your time. 3 is actually a very good movie.
