imho the aspect ratio you may choose for to shoot a specific project is also much connected to the visual "language" you intend to use. There are some real advantages in shooting widescreen (2,35:1 and wider), first of all you could create a 2shot closeup in which the actors are still able to move, come closer together in a fixed shot. Second this format enables you to have a single closeup on one actor and a total shot in one. And third: Since most / normal movement is horizontal this aspect ratio will keep the frame more steady (you don`t need to start panning immediately as soon as a movement occurs you need to follow) which could be essential in cinema (where you are basically forced to follow since the screen will more or less cover your complete field of view and everything els is just dark) in order not to get too much disturbed by a camera movement. Sure, there is also great films shot in 1,33:1 or 1,85:1, but widescreen is imho. quite a good choice if you intend to use complex blocking together with much movement in the frame and still want to keep the picture / camera movement under control. Thats why you bring back the spectators attention to the movement in the scene which enables you to emphasize / accentuate very special moments by using strong camera movement on intention.
