We went to see both this evening. I've never been to an IMAX venue before. It was quite an astonishing experience. The screen is 70 feet wide and 44 feet high, and the image quality is awesome. Fortunately we had seats near the back, so we weren't completely overwhelmed by it. I loved the fact that there were no adverts. I really don't need to see the trailer for Mr and Mrs Smith again, and no amount of advertising will induce me to buy a bottle of Pepsi or the latest Cadillac. And there were no sub-titles. Movies here normally have subtitles in French and Arabic, and they can be quite distracting.
But the star of the show was the show. Batman Begins is an awesomely well-crafted movie. Dark, broody, moody. It looks great and has believable characters. Gotham City is superbly presented as a massive stinking sewer of a place.
I hope we'll see some sequels from this team.
