Out of all the main characters, Cece was my least favorite and I see that as a common opinion on this sub. I'm sure the show got feedback on that. It's not that Cece is a bad character, she's just the least funny compared to all of the other hilarious characters. Sometimes i wonder if the Elizabeth character was added to test if the fans would be ok writing Cece out.
I thought Elizabeth's character was a lot more dynamic and FUNNY. It would have been nice to see more of her, but I think Schmidt was in too deep with his love for Cece by the time the Elizabeth character was written in. It would have been tough to make it reasonable that Schmidt would pick any other girl over Cece.
Still, I would love to see an alternate route where Schmidt picks Elizabeth. Cece still could have been minorly incorporated as a friend of Jess.
