S8+ too long, looks awkward?

As a cinematic pedant, I ONLY watch movies filmed in the preferred 2.35:1 aspect-ratio -- so I welcome the reduction in letterbox-effect that this phone will provide.
 
I'm still waiting for phones to come out in the Golden Rectangle aspect ratio of 1.62:1
 
For those concerned about the aspect ratio, there is a settings menu that allows you turn off "full screen mode" on individual apps. It basically cuts the "curved" portions on the top and bottom of the screen off to make it a normal aspect ratio. You can do that on an app by app basis. At this point you have a ~5.7 in screen. Considering the phone itself is physically about the same size as other 5.7 in screen phones, I really don't see the downside to this. Gives you the option for more screen real estate, but you can turn it off if it bothers you in apps.

Yep, a thinner 5.7" display with smaller content. Kind of defeats the purpose of the bigger display and the curved corners don't help with content that actually fills the screen.

I used the 8+ for over an hour and found the options to be cropped or smaller content. Even web content and reading felt constrained.
 
I don't know about that. Why should mobile phones be shackled to the 16x9 ratio, that essentially came about back in the 1930's or so when cinematic film came out?
Actually, movies were 4:3 (Academy Ratio) since the dawn of cinema. Widescreen started with the widespread adoption of television as a way to differentiate between movie screens and TV. Think of all the pre-50s classics that are 4:3 - Casablanca, Wizard of Oz, Gone with the Wind, etc.

As a cinematic pedant I would think you would only watch movies at a theatre on film (if available) and a big screen.

I watch tv shows and sports on my phone. Rarely watch movies.
