I didn't een know what was going on. I still don't. Really apart from the clones origin (which in the end is nothing else than an extreme elobarate piece of boring exposition and quite obsolete (as if it is SOOOO important where the clones came from... )) the only thing that is a plot point is Anakin and Padme falling in love... And the death of Anakin's mother a little bit. And that is IT!!!
Now if them falling in loe is the only crucial plot point, and the love scenes suck, one can only conclude that this film is flawed to the core.
And yes, you have your clones, fine.... enjoy them. That's why some of us believe that Geonosis might be the best as a BATTLE PER SE.... not as part of a great movie.
But it LED nowhere, only to more exposition.
And the slug scene is part of a sequence that creates a whole web that is closing in on the Falcon: they are nowehere safe. It's a very good scene, well acted, good romance in only a few lines, humor, and a good supsrising twist with a from-the-fire-into-the-frying-pan effect... Dramatically flawless, I can't imagine anything against that scene.
