Scope Ratios are overrated
A lot of films have this really weird obsession with scope ratios imo and tbh, Scope ratios don't make sense a lot of the time? Like why do you need your film to be so wide? And you aren't even taking advantage of it most of the time. It's just wide just because it looks cinematic. Like I saw a trailer for Bridget Jones: Mad About the Boy and it's so wide for no reason. It's a romcom you don't need a romcom to look so wide like that. And the worst part is when it AFFECTS TV SHOWS! YOU AREN'T EVEN WATCHING THEM ON THE BIG SCREEN THERE IT'S LITERALLY JUST A GIMMICK!
And most of the time? It isn't even anamorphic, They're shot on spherical and then cropped. It's a waste of camera! At least flat widescreen doesn't waste so much from cropping it.
Verdict? Unless you are shooting in anamorphic (or 2 perf Techniscope) and can use all of that wide space, Stick to flat ratios.
