Maybe it' my lack of english language understanding but, seriously, I don't get it. How can we have "too much information" with 48 fps? And how can we consider 48 fps as a hight framerate (HFS™, haha, this joke)? It's a very poor framerate. 85 frames per second (and per eye, if you're making 3D content) will be a passable frame rate. 100 is good.
I've played to a lot of multiplayer first person shooters since Quake (Hmmm, Doom in fact), and under a 85 frames per second value you just can't perform well... Because you just don't have enough visual information when you do, for example, a fast rotation. A 180° rotation, in 1/10 second (wich, in gaming context, is slow, very slow), with 24 frame per second = 2.4 poor images (one each 75°, I hope my math are good): Not so much if you looking for Tutu75, an enemy sniper, in the jungle.
You'll say gaming is not cinema, it's an active media, but that's exactly the same problem if you give Stanley a steadicam to film "The Shining", if you want to film StarWar 7, or a new american crappy licence like "Transfomers vs robocop vs Marvel Super heros vs Godzipredator". Fast action, and fast camera mouvements, need a fast frame rate, period. And don't get me wrong, I prefer good cinema.
Does Kurosawa's movies would be better with 100 frames per second? I doubt that. Does it be damaged? I doubt that to. In fact until you don't colorize it, don't change the ratio, don't put some noisy sound effect, and stay in original langage version, I'm good with it. Give me "Apocalypse Now" or " Heaven's Gate" with a 200 fps framerate and I'll push pause button on each frame.
The only real issue I see here is picture editing: Okay, a 85 fps format need more postwork. Calculate CG background is longer. It cost dollars. Others ("press") comments are just new school (young people) vs old school (older people) same old bullshit.
Now, I didn't see the film, maybe it's horrible, but, in this case, I'm pretty sure it's not because of the 48 fps, but because the merge technic of these 48 frames. Also it can be a silly movie. Hoping I'm not too much off topic.
