I do dislike the movie's heavy use of pastels, but I don't think changing the uniforms would improve my opinion of the movie much. The movie's real problems -- pace and story -- would remain the same.
This is similar to my feelings about Star Trek V: The Final Frontier. The movie's visual effects are for the most part embarassingly bad. But replacing them still won't solve the movie's fundamental story flaws.
Hmmm good point. Would have made it more watchable to you?
