-many design sketches, some never used (yup, I like to collect those albums)
-J.Williams score was good, but previous scores were great... great>good
-Darth Sidious holograms... good old Palpie! made me believe I'm watching Star Wars when the Episode I was screened - love those Force Lightnings, too
-Coruscant, esp. at night, also when shown from low orbit - I dig those big CGI cities
-first 10-or-so minutes of E1 (before JJB shows up)
-Jango Fett, Slave I - even with all cons it brings, it was like a piece of beloved ESB for me
-Jango's pursuit after Obi in the asteroids (esp. the blaster-dogfight) and their duel just before
-Republic gunboats - wow, they had Hueys back then! too bad they didn't play Wagner to scare the poodoo from those Separatist scum!
-seal of the Republic, so similar to Imperial, makes me feel so moved and patriotic and...
-Federation's control ships
-AT-TE walker and few similar designs (but not the artillery!)
-"...my little green friend..." - priceless!
-Republican Destroyers (but I hate the concept of huge ships like Acclamator being able to *land* on the planet - if so, why use those Lambda-class Shuttles, Delta-class Transports etc. etc.? tiny legs and loading ramp suck - big ships should stay on low orbit)
-Droidekas (but not their visible shields)
...
...wait, most of those things are from designs department, and this has little to do with the actual movie itself... (storyline, acting, editing etc.)
