I do tend to agree with most of the reviews on here, but I would say that they only hold true for the first couple of seasons. I think I probably watched season one and two and remember the cringe worthy lack of chemistry between the presenters and the complete copy and paste job from the UK Top Gear, but what can you expect so early on? Now watching season five and I have to say it is a much better show, yes each episode is now just one long special/expedition, but I really like it. Yes it may be incredibly scripted and impossible to believe at points, but so is the UK show and it doesn't take away from the fantastic places they drive their high performance vehicles through! One problem with removing celebrity guests, fast lap time etc is that if you don't really enjoy the subject matter (for example drag racing, which I have zero interest in) there is nothing to give you a small break from it. Although it is many times better in its current iteration I hope they bring back something from the UK series.
