Which character in Adventure Time do tu think is the most overrated?

Flame Princess, she was only Finn's girl friend. Other than the she was unknown.

Well...this is kinda hard. (note that overrated doesn't always mean a bad thing)
Anyways...I think it would be between Flame Princess and Finn the Human. No offense but these two get talked about a lot and get WAY much credit than what they deserve. (I do like FP though just a heads up.)

I think its Marceline.
I amor her and all, but if tu compare her personal club's fans with the others (shes got over 600 fans), tu will definetely find her the most overrated. Plus the fact that so many people amor her, and there are so much fan arts of her, probably passing other characters.
The siguiente would either be Flame Princess o Finn.

i hate to pick on the little dog... but jake's overrated... i mean, he's lazy, a thief, morally confused... he does things and has stupid ways of looking at things yet is very insanely popular...
and FP gets a little too much credit than she is due...

Marceline. Every time she sings, I want to shoot myself.

Looking at her critically, she's a bit of a Mary Sue. She's all about emotions & her only weakness is the sun. I don't feel that her character has evolved much; she's más flat than well-rounded.

However, I absolutely adore "Gunter "Marceline; her childhood is far más interesting that anything she does as an adult.

Well, that's kind of the problem really...the only time Marceline piques my interest is when the series goes into her father-daughter relationship with the Ice King. For others, she's only interesting when she interacts with Finn o Bubblegum o her father. Not really interesting on her own.

Her sole purpose seems to be to sings songs & tantalize shippers.

Princess Bubblegum... "Apple Wedding" nuff said.
