There's a lack of color variation... the figure looks too plain.
Yea, that's one reason....
It didn't - *POP!!* - in regards to the visual.
Usually figures that give me that instant - "WOW!!" - are usually worth a purchase.
Simplicity is OK, but at times, there's a fine line (I guess imo) that renders the figure - "dull" - and this is one example.
They wasted a character who has allot of potential by using a such a simplistic pose, simple colour swimwear, colour and static action.
It would have been worth it if they added an extra hair piece, to change it from short to long, then ... maybe.
