Both Jackass 3D and Zombieland 2 are being filmed with the cameras that James Cameron hand built and designed for Avatar. Dude is making a mint off rental and licensing fees and pretty much every new 3D movie will use them.
I absolutely agree with you. Most of these movies do not even need to be shown in 3D. One recent one i saw listed at the movies is Step Up 3D - like wtf??!!? Does the audience really need to experience dancing in 3D??
I dunno - like i said earlier, not every movie should be seen in 3D. With that said, the few that should be seen actually come out very nice. The experience is great! I've seen Avatar, Harry Potter, and a few others in 3D and it was amazing. I guess it also depends on your theater or how the glasses fit your face. My friend said he gets a headache every time he watches a 3d movie at the theaters.
