Jess became the most IRRITATING character
She quickly went from cute/quirky to just annoying and irritating within the first 2 seasons. She's always trying to get involved in her roommates problems and ends up making everything worse with either her bad advice or her own involvement in general. She can NEVER be serious even under the most serious situations. It's cute at first but after having to deal with it for six seasons I just can't get over the thought of how annoying her on screen presence has become. Megan Fox was a great replacement and gave the show the change it needed - a character that can actually be SERIOUS. It brought a great balance to the show since every character has become a complete goof ball including CeCe.
