A solid 8 from me. This is now what TG does best in my opinion, so much so that when a new series comes around it's the end of series specials I'm looking forward to, more so than the series itself. It's the escapism of it all I enjoy so much; a travel show hosted by three mates dicking about.
However, I do agree with Dr Grip to a large extent. The set-pieces he mentioned don't hold the appeal they used to, because you know they're all manufactured. Top Gear is never better than when genuine spontaneity is happening, and even though by its very definition that can't be controlled, I just wish the makers would tone down the scripted stuff and give that spontaneity more of a chance.
