1. The intro of Jar-Jar...that moment took me from the highest high to the lowest low
2. Darth Maul dying...to add insult to injury...why does Jar-jar live and the most bad-ass character ever die, didn't GL learn with having to bring back Fett in the PT?
3. That scene Luke mentioned where Anakin is riding that bull thing to impress Padme from ATOC, awful
4. The Scooby-doo fish scene in TPM, nuff said.
5. The Roger-roger droids
6. Dex from ATOC that analyzes the dart, why add stupid cartoony looking characters?
7. Watto, again why? Why?
8. Definitely the two headed Pod-race announcer straight from Laff-O-Lympics (maybe before your time)
9. Going from one jar-jar to Gungans...again it felt like my heart had already been pulled out and someone jumping on it.
10. The whoopie scenes with Anakin in TPM and the "its not fair" whiny scenes in ATOC
11. The kids figuring out where the missing planet is for Obi-wan scene in ATOC...OMG, are you serious?
12. There is a scene when Obi-wan and Qui-Gon drop down to a lower level over a hundred feet in TPM and its looks soooo cartoony (e.g. the war against the droids in TPM).
13. "why do I feel like your going to be the death of me" from Obi-wan to anakin is bad, really lame
14. Can I just say any Jar-jar scene makes me want to strangle someone. GL maybe.
15. TPM in general was far too cartoony...many scenes used CGI abusively. That said the realism and acceptability for CGI is VASTLY improved in ATOC.
16. Boss Nass
Now that all may seem negative, but I love Darth maul, the double saber, the sound in the pod-race, the fight between obiwan and jango, the dog fight with obi and jango through asteroids, the gladiatoresque scene in ATOC, Obi wan flying through the crowded city, Palpatine in general, the clones and that whole story, saber fights, Anakin wanting revenge for his mother and kicking ass, the ship obi-wan has that dock in the circular thing to hit lightspeed, etc. So hopefully that eases the negativity a bit. Though trust me, TPM still rips a whole in my heart when I think about it.
