Dredd is one of the few times that I have paid out cash money to see a 3D movie, essentially because I'm a huge fan of 2000AD (with a much dog-eared, torn and graffiti-ed copy of issue one in a box under my bed), and there are no 2D showings within sensible distance. Three dimensional movies give me a three dimensional headache, invariably leading to very much three dimensional rich, brown vomit in the car park afterwards.
