Yucky is rude? How about hideous, misshapen, fat, bulbous, and just downright ugly? Read the rules of the site. All these criticisms are acceptable, and a matter of opinion, and do not violate the rules (sexual content, profanity, etc.). Just because YOU don't agree with them does not mean the comments are "rude". However, you chastising another reviewer because of their comments, even when they're not violating the rules, goes against the spirit of the site rules, if not the letter of them.
