3d sucks so it's not surprising the rest of the world likes it.
		
		
	 
atot and the nerds of the internet hate anything popular, so it makes sense that people on here hate it.
3d just adds another visual element to it.  people saying they "hate it" probably have never seen a nicely calibrated 3d movie, or they are one of those people who get headaches or simply can't enjoy it due to being uncomfortable.
that said, there are definitely some movies where 3d just doesn't add anything to the movie that would make it better than the 2d version.  one such movie that i've personally seen is world war z.  i got the 3d bluray because it was like $16 and after watching it, i would have been just as happy watching it in 2d as 3d.  
but then a movie like many animated flicks such as finding nemo or wreck it ralph, the 3d just adds another dimension to it that makes it visually more enjoyable.  same with jurassic park in 3d.  it adds another element. 
definitely not surprised that atot doesn't like it for the most part. most people here don't like anything that is fun or popular.
