Aren't those questions you ask yourself when you see a frame like this?
Nope. But that's just me. I've made my peace (for the most part) with the fact my preferences are often at odds with those of others, and the artistic community at large. I respond differently, I guess.
Ha! I've always thought Muybridge was interesting.
Actually this is the work of Etienne Jules-Marey, though he was a contemporary of Muybridge and there is some history between them. Jules-Marey was a real scientist though, who used his camera for legitimate investigation, whereas Muybridge was more of a photographer turned scientist, or at least that's the general idea given in Marta Braun's Picturing Time: The Work of Etienne-Jules Marey. He pioneered a lot of these early sequential methods, and some would say he invented cinema, but that's a different tale altogether.
Not unlike Edgerton's later investigations with the Xenon flash tube.
