Harry Potter at the IMAX London, which has the largest screen in Britain. To give you a rough idea, the screen is about 4 storeys tall.

Can't remember how much the tickets cost, as I booked them back in June, but IIRC, they were roughly in line with London cinema prices (so ,about £11 to £12). Large popcorn and coke for £3 each item.

Popcorn tasted microwaved, but was no better or worse than the popcorn at my local Vue cinema (and the prices were slightly lower, and the service considerably quicker).

The trailers were all presented in 3D, so we had lots of clips of dinousaurs poking their heads out of the screen, and walking over the camera, which caused most of the audience to jump. The 3D looked amazing and added real depth to the picture.

8/10

Then, on to the main film. It was amazing. It was exciting, possibly slightly scary for kids, and funny in places. The battle at the Ministry of Magic was presented in 3D, and, while in places, the two images weren't aligned properly, it did look amazing.

Oh, and the 12KW , 40 channel sound system meant it was loud and sounded amazing.
