i like it 🙂
alice in wonderland was awesome, loads better than avatar i thought (though avatar was pretty awesome too)
just remember to look where the director wants you to look. if you try and resist, and look around, it all goes wrong as its all out of focus.
also, on avatar, the filmed 3d bits, and the rendered CGI 3d bits were a bit "out" so i found i could see the joins (or at least it didnt sit comfortably), however there are scenes in Avatar, where there is no CGI at all, like the bit in the jail cell, and thats incredible to look at as there are no discontinuities in the image.
i know a few people who have said they would rather see the films in 2d though.
i think its a personal experience thing.
just give it a go and see!
