You do realise you can turn off the shaky cam, right? Also the blurry visuals.
Over in the Steam forums we've been discussing the lack of multiplayer. Everyone is "THE CAMERA SHAKES!!! arrrr!", and the response "Options, uncheck shaky cam". Three posts later, "THE CAMERA SHAKES!!!! Aarrrrr!!". So have to check.
Also, I believe the term is "stylistic", think Sin City, Watchmen, any of the wuxia films like Hero or House of Flying Daggers. Even Quentin Tarintino, very pulp. It was a nice change from the Halo clones like CoD4/5/6, Battlefield BC2, etc, ad nauseam. It wasn't Hitman by any means, but it was new and something that hadn't been tried. I'd even go so far as to say it forwards the "Games as art" argument since they did it so well. Granted, the plot was.. Well.. And the scripts.. We can agree it mostly sucked, but I maintain it has it's moments and is overall worth playing. Simply because it isn't generic.
