The presenters try hard, perhaps too hard. They have big shoes to fill and (at present) they aren't doing too flash. They seem to try too hard to be Clarkson, Hammond and May with Australian accents. In particular Warren Brown is taking the role of James May - not particularly car savvy, 'Capt Slow' and the butt of the other presenters' jokes. The other two are the race drivers and petrol-head hoons.
The show may settle in , if it is given time. Old episodes (1989 and early 1990's) show that this show has evolved a very long way.
The staging is a clone of the UK one - a mistake in my view and "The Stig" is a direct (and uninspired) rip-off. Their test track also seems tame and uninspired compared with the UK one.
