In my opinion, Top Gear is well past its sell-by-date.
I loved the old format as a show for car nuts only. It was quietly enjoyable and informative. Clarkson brought humour and pathos to it with his more emotive and entertaining reviews. He was an outstanding journalist at this time in my opinion, stiking the right balance between getting the facts across and providing entertainment.
In the early years of the new format Top Gear, I feel that again, the balance between entertainment and quality, factual content was about right. It breathed life into motoring shows and the challenges were genuinly entertaining. The natural chemistry between the presenters led to humour, but the humour was secondary to the content.
Now we have reached the point where the balance has tipped the wrong way. Every episode is geared up to provide humour first and quality content second. What makes this even worse is that the humour in question is of the lowest variety, seemingly geared to please the "chavs" and "barrys" of this world. Drawing a penis on another presenter's face? Wow, we're really moving comedy forward with that one.
Clarkson for his part has become a middle aged joke. He no longer looks cool in that early Top Gear euro-fro, jeans and leather jacket mode. Quite apart from the fact he is aging rapidly (which comes to us all), he seems to delight in looking as aged as possible. Instead of carefully considered opinions interspersed with cleverly placed humour, we get wildly overstated remarks with outrageous, extreme attempts at comedy. His opinions are worthless because they are so over-the-top and lacking in credibility.
Hammond seems to have fallen into a similar trap. I enjoy watching May in his own programmes, which are always very intelligent and well put together. On Top Gear, he is increasingly isolated. My bet is on James leaving some point in the future.
So my general view is that Top Gear is now a cheap ratings winner and should be brought to an end. One day, the mass audience will desert it (being so fickle, witness other programmes) and it will die an ignominous death. This shouldn't happen.
By the way, Rich Hall's Rover song was very funny...
