It would seem that fans have a LOT of fears regarding Episode II, so much so that we'll get on with your responses:

• Hope this movie is more for adults than for 10 year olds like that last one.
  by Kimberly
• I don't want lucas to stray from his vision to compete with other movies coming out. Or a character to be involved so kids will like The movies ... His audience isnt the 5-13 demographic anymore.
  by Jay Howell
• Too little violence
  by arinblah@yahoo.com
• That it will have a horrible story or will be directed badly
  by Brian Taylor
• That people will have to high of expectations, just like with Episode 1.
  by Trent
• Incorporation of EU into the film
  by Darth Zome
• That it will suck
  by Jorus C' Baoth
• That the script will be as a bad as that of episode 1, if not worst?
  by Dor
• Lots of jar jar
  by michael
• Too many pretty clones, cool battles, etc., and not enough storyline
  by Mr. White
• That it really IS called "Attack of the Clones"
  by Proctris
• Avoid experiments of any kind. Try nothing new that could be considered as "non star wars" as we are used to know it. It?s a simple formula but it?s essential.
  by Digitalfun
• That whiny fanboys will ruin the movie when their militant expectations are not fulfilled 110%.
  by Chandler
• I fear that Episode II wont do as well as it could of because of The Phantom Menace, which in my mind was a great movie.
  by Kyle Stubbs
• Yoda?s Fight
  by Othmell Rodriguez
• There's a rolling blackout at the theatre right as the opening crawl starts....
  by Steve N.
• Fears? I find your lack of faith disturbing.
  by ObiWill
• I fear the dialogue is cheap, weak and contrived--particularly with Anakin as it was in TMP. That will ruin Darth Vader for so many of us!
  by Darthmaul_one
• That the love scene's are going to be contrived and not really truly developed.
  by Evan
• That it will be boring and too short
  by Angel
• Lack of skepticism. Perhaps Jar Jar should have been developed into a skeptic instead of a comic in Episode I. I agree with Hamill although i doubt those comments were actually his own thoughts.

• C3PO turns out to be Luke's real father.
  by Dave F
• My worst fear is poor character development
  by DasJerm
• Too much CGI
  by jason
• Yoda's battle looks funny
  by JarJarFields
• It still fails to be as good as 4,5, and 6...cause then we'll know 3 will be bad too
  by Jordan Liles
• A martial artist Yoda (cringes)
  by Sauron
• My greatest fear is that it is going to live up to its title!
  by Beastie the Hutt
• A Jar Jar song and dance routine.
  by Rett_Brone
• The failing of The Phantom Menace is that the characters were not real everyday people we relate to and want to cheer on. My fear is that AOTC will be more of the same.
  by Bryan D.
• Won't make the vital link between EP1 and classic trilogy
  by maulster79
• I fear that ATOC will depart from what makes Star Wars stand out, that is the engaging story and realism of the characters (this is what happened with TPM).
  by Chris Wells
• Bad acting
  by jeff
• Cinematography not on par with the OT
  by Debo
• It will have no heart
  by Dudewalker
• It will be no more than a fancy computer game
  by Dudewalker
• I fear another discourse on the function and form of Midichlorians during the first 20 minutes of the film
  by Joseph V.
• It will simply be a collection of shallow action sequences
  by Dudewalker
• It will be shallow and uninvolving like episode I
  by DarthQuixote
• It will be the laughing stock of Hollywood and provide an endless source of joke material for late night chat shows
  by Dudewalker
