i dont think anyone thinks its bad they are both great games of my childhood

I've heard that about Sticker Star - the story is boring or smth - I haven't played it myself though, however I've never heard that about Color Splash and having finished it myself, I'd say it's even better than Origami King. :)

Because its not TTYD

Because it's... NOT THE FREAKING THOUSAND YEAR DOOR!

i didn't like the thousand year door

It's prolly because IGN and other game critics rated it poorly to the point where people followed and agreed to their opinions without (maybe) not even playing it. This was also the case with Sonic aswell, sadly.
