If you're thinking of watching it in 3D save yourself the money and dont bother. The worst 3D i've seen in this new batch of 3D films.
The film is pretty rubbish too!
Went to see it today in 3d, it was an average movie nothing special definately not worth paying extra for 3d as it didn't even look like i was watching it in 3d! My little sister enjoyed it though.
The 3D was disappointing for me, I like the 3D to leap out of the screen at me and this didn't, was more about giving depth to the film.
Not worth the extra imo.
