I can't judge the list completely because many of those I saw in 2D.
But I thought Alice in Wonderland was terrible 3D.
And I actually don't think Avatar is the best 3D, even though it's without a doubt the best movie on that list.
Other than that it's a pretty good list.
Jackass 3D - 4/10
Saw 3D - 7/10
I'm surprised Friday The 13th Pt 2 was on there.
I didn't see any of these movies in 3D (Except part of the terrible Avatar), so I wouldn't really be able to tell.
I did think Saw 3D had flawless 3D imagery though...
