Back now and can report my experience.
This is a 3D concert film experience review not a U2 one, like them or loathe them for their music, lyrics or politics, that can wait another thread
Well I saw the film at IMAX with the mega big screen and integrated 5.1 surround sound audio.
and well................ Wow!
They certainly stitched up the pirate film copiers with that one - it's going to be some years before anything close to that experience is going to be available in the home setting - I'd say a virtual reality headset with built in head phones would be the only possible way of replicating that.
Firstly, yes it was a sit still and soak it all up experience - I didn't hear anybody singing along, although the volume was sufficient to cover the few that did. I would imagine trying to move around with those 3D images floating about would be quite vertigous.
I loved the intimacy with the band, the crowd. Once or twice I wanted the audience in front of me to stop waving their arms in the air but then realised no matter how close they seemed the arms were from the concert crowd as the camera dipped down to film from the audience's perspective.
Not a medium for any artist worried about their appearance, as appearing twelve foot high a mere two metres away from the viewers perspective reveals every wart, blemish and drop of sweat there is going.
I am a technophile by nature fascinated with the mechanics of bringing a live concert together so being on stage with the band for long periods I could look around at the paraphanalia they use to bring the sound and images to you.
Imagine hovering eight feet about Larry Mullen Jnr as he beats his drums into submission or rotate round behind him and see the audience from his perspective? Awesome.
U2's art directors couldn't resist floating a few images out into the cinema to grab, but on the whole they avoided gimmickry.
One nice moment when Bono drew out an image with his finger that came alive as he wrote and again this floated out to the cinema audience.
I'm suprised the screening carried no warning at the ticket desk, or before the screening, that flicker-sensitive epileptics might struggle with the film, I suppose it's just a gimme that those that know they are sensitive do not go to this type of event.
Filmed outdoors at a stadium concert the 3D imagery really brought home the space the band fills with light and sound - the quieter "hold your lighter/mobile phone in the air" moments were magical.
If you go, don't rush out at the first role of end-titles they run over Yahweh and after a few moments the band reappears singing the song between the blocks of credits.
I always arrive early enough to be amongst the first in to get the best seats (half way between projector and screen and central) but the IMAX system is quite forgiving for 3D images if you are further forward or to the side.
Not a bad evening out with, here in the UK, a family of four ticket deal costing £28.00.
So with the right production/direction and staging I can see other 3D concert films being produced successfully.
As usual, as often the way in these things, this film has collided with the cinematic release of The Rolling Stones own (2D) concert film.
I'll be interested to read direct comparisons as to the "experience" as a cinema goer.
I don't follow The Stones sufficiently to warrant going in order to make a personal comparison.
