This is the latest way for the movie industry to get people back to the theatres. Now we've all got big screens and HD the living room is looking increasingly appealing compared to the out-of-focus, crappy print quality, fast-food, daycare centres of the multiplex.
But if they can now offer 3D that's something you can't have at home. So for a couple of years people have been drifting along to see the novelty - some good ('Up'), some bad ('Clash of the Titans') - but all highly profitable as they've been able to bump up ticket prices.
Where it all falls down is that people who actually *like* 3D are few and far between. Even those movies that haven't been post-produced to look 3D (hello 'Last Airbender') tend to look a bit murky, are hard work on the eyes and come across as LESS immersive than a well-projected (especially digitally) 2D movie. I'd be perfectly happy never to see another 3D feature ever again outside of a theme park.
So no, 3D won't persuade me to buy a new set. Bigger screen, better blacks, Internet out of the box - yes, thinner - maybe.
And if they want me back in the multiplex - well tasers for the staff, a projectionist who knows what the focus does and content that doesn't assume I left the brain at home would be a good start.
