Besides being pretty robotic, Grant has a voice that's pretty cringe-worthy at times. No offense to the man, but it's true (at least for me)
the editing at times feels "too safe", usually a generic happy/sad/sucess!/failure music plays whenever something happens. The show rarely tries really unique and complex editing techniques, it's a little disappointing, but not really a huge deal, a little more variety in editing would have been better though.
TARAsia is terrible imo, please stop copying, even if the tasks copied are a million (nay, a billion) times better rendered.
less obvious "cannon fodder" teams and strong teams, the season's boot order was very predictable
A little better leg structure planning (remember the dumb intersection right before the pistop? or 3 stinkin' luck task in the finale)
Shorter recaps at the start of the episode, why do they need to be so long?
The show's a little cheesy at times, it's rare, but it happens.
subtitle for people with an australian accent as strong as Matt's (btw, they were my favorite team, Matt and Tom, if only I could understand Matt more).
Less emphasis on scenery (too many zoom shots) and more on the teams and on the race.
Don't lose the Marked for Elimination penalty, it's the perfect penalty, the speedbump is progessively getting worse and worse.
That's all I have to say for now, I still love the show, it's the best TAR rendition yet, nothing else came close.
