And yet Cameron ensured that the T2 3D re-release was solely 2.35, go figure. Personally I want to see what it was originally framed for, even on Super 35, and not some open matte version that's usually done solely to appease the black bar haters. I dunno how many movies you've watched on TV lately but the main terrestrial channels routinely broadcast in 2.35, just a week or so ago I watched Good Kill on C4 and Fury on C5 and both were in proper widescreen. They were shot anamorphic but even so, they'd have cropped them to 16:9 if this was a few years ago but now I'm still amazed how much proper 2.35 content we get on TV. Even some TV shows are broadcast in wider ratios like 2.00:1, and others are full 2.35.
So far from TV being the death of proper widescreen, it's seen it flourish. Lots of adverts are even shot anamorphic now. Sure, not EVERY movie is shown in full widescreen when it could've been but it still amazes me how far we've come. As for IMAX, if every cinema were an IMAX then you might have a point, but they're not so you don't. I saw the open matte 1.78 version of Skyfall on ITV a while ago and couldn't stand how much dead space it had top and bottom, it was framed up for 2.35 by one of the best DPs in the business and it shows.
I'm just happy to take whatever ratio a movie was intended to be shown in, no matter if there's black bars on the sides, bars on the top & bottom, bars that come and go.
