Finished the new episode and thought it was okay if you take it as a new show. Chris Evans was trying too hard and shouting too much. References to the old hosts felt forced but kind of required. I thought Matt Leblanc did a good job. Apparently they've separated the show into two parts with a new show called Extra Gear. So Top Gear will be the flashy parts with stunts and celebrities, and Extra Gear will have people who actually know about cars doing the news and behind the scenes stuff.
I'll give it the chance to grow out of the shadow of the old show, and keep waiting for The Grand Tour on Amazon.
