I thought so.
His biggest problem was playing second fiddle to Evans. While Evans seemed to be trying to channel Clarkson, and failing abysmally (as well as just being an annoying twat*), LeBlanc was just being himself - and seemed to be getting more comfortable presenting as the series went on.
* I enjoyed Don't Forget Your Toothbrush - but I was a lot younger then. I've found him annoying ever since, though.
