I thought this was the weakest of the series so far. I didn't think it was crap or anything, but they've done everything they done already (amusing impracticality of certain cars in cities, driving fast across some terrain). Seeing the GT-R on the track was the best bit for me.
I've said stuff like this before, but i'd enjoy the chase bits more if they didn't try to hide the camera/crew/camera-cars so much. Those imperfections add to the feeling that they're concentrating on racing, not filming, and make it more exciting. See: the Japan race last week, where you could see the crew even talking to Jeremy as he had to run the last phase of it.
Instead, here we got pretty shots from up high just after Jeremy stops and pretends to realize he can't cross the river, even though its obvious the shot is from somewhere it would take the crew 5 minutes to get to before hand. That just breaks the excitement of the race in your head. Filming directors need to keep in mind that the end goal isn't how cleanly or how prettily it can be filmed, its the end result in the viewers mind, and if faux-bad-filming enchances that, do it.
