First of all - I didn't know we HAD that many fans in Delhi. They cheered and applauded at the opening credit thingy and the scrolling yellow wordy bit. They also, for some reason, cheered at Padme's pregnancy. Applauding her fertility, presumably.
So yes, I was surrounded by screaming fans, and most of the time that was a really good thing.
ROTS is far, far better than either of the prequels. The effects are stunning. The dialogue is slightly better than the last two (though Padme/anakin scenes are still rather cringeworthy). The acting is mostly better...Natalie Portman didn't impress me much, but Hayden got better. What really sets ROTS apart from TPM and AOTC is the fact that you actually care about the characters. Anakin's transition to the dark side was painful at times, as was Obi-wan's feeling of betrayal that Anakin had not carried out the prophecy. And some of the strongest scenes in the movie are done without the characters spewing 'dramatic' dialogue - Anakin and Padme sitting silently looking out of the window, Vader entering the Jedi temple with an army, the younglings scene, and the masking of Darth Vader. The betrayal of the Jedi, shown for each individual, is pretty heartbreaking. Padme gets the best line in the movie, as she watches Palpitane turn the republic into an empire.
Yes, the movie had its silly bits. General Grievous is just annoying, and walks like the smaller, brown dinosaur in Dinosaur Comics. Obi Wan on a giant lizard is really rather silly, but it doesn't jar. As usual, C3PO and R2D2 provide comic relief, R2 is especially brilliant (I'd never noticed before how much he sounds like a teletubby).
I think what I really appreciated about the film was that it wasn't all black and white. The original trilogy was, and that was good. But most of those who were children when they saw the originals are all grown up now, and presumably have learnt that it's not that simple. Some of the Jedi actions are dubious, and there is good in Vader. And the movie sets things up for his redemption brilliantly, I need to watch the original trilogy again. It'll have more depth now.
So, this is how liberty dies, with thunderous applause..-Padme
I'm weak! Don't kill me! - Palpitane/Darth Sidious.
